i agree with the above post. the proto ct is good at everything, but does not excel at anything. that said, it's a freestyle board which is what it's geared towards. it's weaker on the butter/jib side and stronger suited towards the carve/jump side.
it's a bit grabby, and can get squirrelly because its so easy to initiate turns. i wouldn't say these are cons though, more like attributes towards the proto which make it what it is.
the more i ride this thing, the more i fall in love with it. i dont find the need to really ride anything else.
if you're going to buy this board, i would say do not size down from what you originally ride unless you plan to go all park/jib.
