I think the Lizzies would kill for what he is talking about. I have owned both Lizzies and Reno Rockers.. and this is my take. I am 5'9 and 140lbs.
Park (Rails): The Lizzies are fat and you have to work a little harder to throw them around, they are also heavier than the Rockers but its not very noticeable on your feet. But the Rockers were long on me so not much easier to throw around. The rockers were a bit quicker to bite an edge for switchups, slightly easier to spin on and off. The Lizzies were more stable on rails and in presses due to the massive width. Both are amazing for presses and butters and the soft flex on the Lizzie is equal in this area to the 'Rocker' on the Moments. I prefered the Lizzies but that is pure preference and both kill it.
Park (Jumps): Again its preference, the Lizzies were heavier but the Rockers were longer. I liked the stability on landings of the Lizzie due to the width. But both the soft flex on the Liz and the rocker on the Moments can make it hairy if you land backseat. You can get 171 Rockers now and those are gonna be much quicker both on rails and jumps. They are both equally good in the park, it just depends on your preference.
All mountain: Lizzies = Win. As long as its not ice and you aren't racing then I love these skis with their snowboard sidecut. So much fun, great to carve. Bit hairy at very high speed but otherwise great. The Rockers have a really long low rocker which is great for park but makes them slow due to low contact area despite fast bases, they also chatter like mad at high speed. In moguls I found the centremounted 181s much more awkward than the width of the Liz, and the soft flex made moguls pretty fun. The rocker is quicker edge to edge and can also carve pretty good, but I would take the Lizzie here due to better edge hold, better carving and amazingly, better at speed.
Pow: Lizzies again. The 110 underfoot makes way more difference than the Rocker on the Renos. The low rise tip of the Lizzie can get divey but the Rocker feels more or less like any park ski in the pow. Its slightly better but that is all. Lizzies are a pretty good pow ski really if its less than say 2 feet then you'll be good.
They are both great skis and personally i'd give the Lizzie a 9/10 and the Rocker an 8/10. I am not sure why I just posted such a massive chunk of text about these two skis, but I am currently bored. I think the ON3P Jeronimo might be a good compromise between the two, quicker edge to edge, easier to spin and lighter than the Lizzie and better all mountain and pow than the Rocker.
I would look at all three and see which fits your skiing style and aims. If you want to learn to do ten switchups on one rail and spin 430 on pretzel 430, have some fun pressing and buttering and hit some jumps then go for the Rocker, which is a pure park ski really. If you want a fun, playful ski on groomers, amazing stability on rails, fun for butters and presses and good pow performance go for the Lizzie. If you want the best all mountain ski that is good in pow and quicker in the park than the Lizzie, then go for the On3p Jeronimo. If you can even be bothered to read this, then good on you.
