I've read some SL vs Proto threads-- it all seems pretty comparable
SL is slightly setback in stance and sidecut, with a slightly narrower tail, Proto is true twin
SL is more damp, Proto gives you some more feel for park stuff
Both have around the same stiffness with the Proto being slightly less
I believe Proto has more pop but I've heard they're comparable and I know the SL got a bit more pop for 12/13 so negligible difference
Proto has blunted tip and tail as well...
SL has soooo many different colours available, and I have the feeling holds its edge a bit better on hardback or ice that we have out here.... Would be nicer to take to a big mountain trip too
..... But the Proto has the fu(kin sick carbonium topsheet
All in all, I'd leave tonight with either of these two boards feeling like a champ lol
Here's a good comparison
