Like I said in my original reply, the Evo is going to be perfect for you, EXCEPT when maching. You say you like doing alot of park, AND going fast, so there will be a tradeoff.
At 152 either board will work very well, you just have to understand the limitations. I have a '54 proto at 175lbs and am adding a '54 Evo to my quiver (going super fast is less and less important to me). The Evo is going to be easier to manipulate for you in EVERY way, but it WILL flap if ur bombing. The proto is basically an advanced version, it will be harder for you to ride in the park, more work to manipulate in general, but it won't flap on you at speed.
Go slower and get the Evo or ... not.
Perfect, thank you. I think I would rather have a slightly "funner" board at the sacrifice of a bit of sketchyness at speed, so it sounds like the evo is my best bet. Hopefully it will be a bit sturdier than the circuit without losing the fun feel that I love!
