At your weight and what you're looking to do... If I were you, I'd definitely get the 154.
I think a black topsheet would look pretty sick and make the colors on the Proto pop, but... it will also blend in with the rest of their carbonium boards since they are all black. I'd still personally choose white for that fact. White carbonium looks sick.
They should do a carbon fiber colored carbonium topsheet. That would be really awesome.
Hmmm, carbon fiber carbonium topsheet... new ideas for 2013 possibly?
