Haha, I had this same conundrum... ended up with both! Specifically the 161.5 T.rice HP and the 158 Proto CTX. Just for the record I'm 6'3" and 180 lbs, size 11 boot. I ride the Proto on smaller mountains where I am playing around a lot, throwing 180s over rollers, looking like an ass in the park etc. I ride the T.Rice when I'm riding faster, bigger mountains and larger jumps. The Proto is definitely more flexible, and would be the option for boxes and rails if you plan on getting into them. I have found that the T.rice floats better in powder, holds a better edge, and can carve tighter, but is more cumbersome in the trees, moguls, and at the slower speeds associated with jibbing features and smaller jumps. The Proto also feels a bit lighter, and is easier to spin in my opinion. The Proto also has a much more durable topsheet (cool bumpy texture) and has full wraparound edges (adding to durability), but that "beans" topsheet on the T.Rice just doesn't hold up and it doesn't have wrap around edges (and the pointy tip for riding powder).
