overall, any of the Rossi Sratch series is a good choice. Stable in the air, stable riding switch, fairly good on rails...a lot of twintips these days are focused on one area of the park, i.e. the jumps, pipe, rails, etc. meanwhile, the scratch can handle all of these elements fairly well.
if u can, try riding a bunch of them before making your decision. everyone's unique so what i find great might not do you well at all.
