I'm 6'3", 200 lbs, and ride a 161.5 T. Rice Pro, a 157 Proto CT (158 CTX last year) and before that I was only carving and had a 166 Arbor A-frame.
I like the T. Rice most for all mountain riding, and it is similar to the Legacy, but I'm sure a lot of people on here will tell you that. I actually tested a bunch of NS, Rome and Lib boards in CO a few years ago and fell in love with magnatraction on Lib rides.
The T. Rice is nice since it is a mid wide. I'm an 11 boot, so most wide boards are too wide for me. The Lib Skunk ape is also good, but only for at least size 12 feet.
Just remember that with the new hybrid rocker, you really don't need to go that big to still float. Even my 158 Proto CTX rides good in powder, not as good as the 161.5 T. Rice, but you get the idea.
