Replying to High end bindings, an explanation and review.

Although the average skier doesn't really need these I think the information should be a little more available. All companies make a "race stock" or high end binding. They are typically made with more metal than consumer bindings, therefore they are heavier but more durable. They come with a higher din range going up to 15-20. They're usually designed to be mounted onto race plates so they don't come with lifters (good for jibbing). The main reason you will see pros and other rippers on them is the durability issue. I've destroyed every normal binding I've skied the park on. Marker frees, look/rossi pivots and new px/axial2, and salomon s914's, they crumbled before my sickness. Had to step up to the race stocks.
Here's a quick review on the race stocks that i've used:
Look P15/P18 rossi fks155/185.
Pros: stong and durable, pivot heel
cons: no multi directional toe release like on their consumer bindings. inconsistent heel release value, difficult forward pressure adjustment, brakes can't be swapped.
I skied these bindings on a lot of different skis and had some scary moments when I really wished I had that upward toe release. The screw pattern in the heel is very narrow so they can't be ripped out pretty easily if you crank your heel din up high (which I don't reccomend). The brakes can catch and get bent down on a switch landing and you just have to bend em back which isn't a super big deal until you do it a bunch of times and the brake just snaps off.
rossi fks120
A junior race binding, it has the same heel as the other fks's but has the multi direcional releasing toe. A great binding for the lighter guys that still go huge.

Tyrolia mojo20 freeflex+17
The mojo20 is like a freeride race stock, the heel has more metal than the 15 and is therefore stronger and heavier but you can't ride your din low enough for the binding to really be useful for jibbing. The freeflex+17 is a really sweetass binding but the freeflex system gives it a lot of extra weight. So if you're going to go with tyrolia, I recomend just using the Mojo15.

Salomon S916
My favorite so far. Five screws attach the all metal heel to your skis, which means no rip outs. The toe piece is all metal as well and is still adjustable to your boot toe like the consumer versions. I haven't ridden this binding for long enough to see if the adjustments will come loose overtime. Lighter riders beware, the din only goes down to 9.

I have yet to ski these but they seem to be super burly.

Marker has some offerings, but I hate marker and don't know crap about their race stocks. I don't really know crap about atomic either so I won't list them. Fischer bindings are made by tyrolia, I haven't played with them myself but I think they make a 17 din version of the mojo 15, It's probably a solid binding.

Most shops don't carry these bindings in stock but they can be special ordered. Just be prepared to pay around $300. Seems like a lot, but for a binding that will outlast your skis it's not bad.
