Am I on to something, or just stupid?

Ignore my last post, my computer is drunk. Anyways after skiing 4 pairs of skis last year in this order el reys, chronics, halos, and Thalls, I had this theory about cambered vs rocketed park skis, with the el reys they held rails really well and were really easy to spin with off of rails, but too stiff for me, so I traded my buddy for 2013 chronics but I found that I would be slipping off the rail more than usual and they didn't seem to grab as well to spin off, then I got halos and experienced a lot of the same as with the chronics, then at the end of the season I rode some thalls (current ski now) and I got that hold back on rails and was able to spin 4s off with basically no drop as I could with the el reys. So the bottom line is I had the theory that since the thalls and el reys have a lot of camber it helps you hold the rail better, because if you think about it, its basically an upside down U shape and that should hold a rail better than a more rocketed shape (I know halos and chronics still have camber but not nearly as much)... If this made sense to one person I'll be happy enough haha, hopefully I'm not the only one who has ever noticed this

It makes sense in theory, but even rockered park skis have a bit of camber underfoot. I think the real difference is the width of the ski and how sharp your edges were and the rails themselves.

That is a possibility with thalls and el reys being pretty close, but the el reys were sharp and the t halls were pretty dull, I mean no doubt edge sharpness plays a huge role but this was still in the back of my head all summer.. nevertheless I went for the new t halls just to be sure I'd likemy set up this year... DDon't plan on going through 4 skis again this year

Nah I thought it was just a commonly known thing. I'm pretty sure it says it in a rocker vs camber thread I'll try to find it

I've heard people bring up this same argument with snowboards. Personally I don't think it matters. The spinning off rails thing though. There might be some science behind that. If the skis have different swing weights it can greatly affect how fast you can spin them around.

Yea swing weight is definitely a factor... I mean hey I'm gonna ride whatever works, but I just thought I'd throw it out there to see what people think

Found one website talking about camber vs rocker that said jib rocker (early rise tip and tail then flat) helps grip the rail better. Couldn't find anything on NS but im almost sure i read it somewhere

but with more rockered skis it is easier to do switch ups/spin off without catching an edge because you don't have to jump as high

Yea that makes sense also but I've never really had trouble catching edges buttering, surface swapping, or on a switch up with a cambered ski either. Not trying to say I'm insane and never catch an edge, I just didn't notice the difference going from a full camber to park rocker ski.

so true. its amazing how much difference a tip being flipped up 1cm rather than flipped down 1cm makes. The collective 2cm difference can be the difference between getting your tips over and the spin around, and not.

with this in mind, i still dont care and ill be using ar7s this season

AR7s are dope skis, I tried them out a year ago but with me only being 155lbs I went for the t halls because they a little flexier. Same dimensions tho.

There is definitely some truth here, I think swing weight has a lot to do with it because my 07 Anthems which are very dull lock on and are easier to spin off with than my 2012 Chronics even though they are narrower and sharper.

Yea, I think it may play a small role just because it seemed to hold true with every camber ski I used (and vice versa). BTW I loved my anthems when I had them... Almost went with the TCs this year because of it but I couldn't get over how good the t halls I skied.. I'd like to get some cheap old anthems again just for shits and giggles tho.

Glad a few people hear me out on this one, I guess I'm just one of the guys who's never gotten the advantage of early rise in a park ski. I mean it totally makes sense in my JJs in the deep stuff it helps you float, but for a park ski you still have the 2 main contacts at the tip and tail and longer and more useless tip and tails causing the ski to feel smaller than it is yet be bigger, for example I got 176 thalls but if I were to go for halos I'd go with a 181 due to the early rise... Kinda seems like it takes away from the low swing weight idea of those skis if you just have to compensate with length... Idk that's just my opinion, like I said before its all personal preference

this shouldn't make any difference. Think about this: when you hit a rail your skis bounce up and down because of the impact they get from the rail, so the camber on the rail is really not that stable hence it wouldn't "hold you better on the rail". It really is more of a sidecut topic.

I understand your point but I feel that the ski still has a push to the center of the camber (mostly closer to the bindings underfoot where it is stiffer) whereas a more rockered ski will have more of a push off the rail due to the lower amount of camber... I'm majoring in engineering so I think way too deep about these types of things haha

But eventually your skis will stop bouncing and just start sliding if its a long rail or softer impact, so then i think it may be a camber issue

notably yes, but with the most skis it's a camber-height of maybe 3-6mm (per ski) and there are always vibrations on the ski, because you also move slightly on the rail.
Maybe there is a slight impact on the rail ability, but there are some features of the ski that I think affect this way more.

haha I know what you mean, I also studied engineering and now it is my job to think deep over this sort of issues every day. But in my opinion the camber shouldn't really matter in this kind of situation. But maybe it is, would be interesting to do some prototypes with similar sidecut but different cambers and try it out.

Oh nice! Its a great field! And yea, I guess the only way to really know would to have two identical skis other than the rocker so there are no other variables like you said

That would be awesome! I would definitely be interested to see the outcome, seeing as so many park companies are using the "park rocker" concept.

there is a reason that most comp level skis are not rockered. this also goes for snowboards too. shaun white rocks a traditional cambered board for park and pipe too.

I noticed that also, I mean you see the pros promote the rocketed park skis (they have to, they're sponsored) but as you said you don't see it nearly as much in comps. There has to be a reason even if it isn't the one I stated

In this case I think the reason is the longer effective base and edge lenght you get with traditional camber - so better edge control and more speed. Rockered park skis are more for jib usage like buttering and pressing

Yea I think that is the other half of the reason why I prefer traditional camber

I've never hit a rail on a rockered ski, I feel like it would be different, but fun. I must try it.

I thought the title was 'am I on something or just stupid'... Anyway I used to have some threats but switched to domains and personally I like the domains better for everything. And they are about as camberless as skis get

OP, your theory makes sense to me...

theory is correct, but its not a big enough foot print to make a difference. youre really only sliding on ~6" underfoot. there is not enough camber or rocker directly underfoot to cause a big enough difference. plus if you are doing the super scissor things where you press really far out on one tip to get a dec spin out your ski flexes enough to eradicate the effects of the shape of the ski.
so, youre just stupid ;)

Hahaha I was waiting for someone to finally call me stupid since its in the title. I kind of figured it was too small of a difference to be worth anything but just thought I'd post it cuz I haven't heard anything on it before
