I have tested both long WB version frames
Ride wise Controll is litle more suitable for real trials, natural, comps etc. Geometry suits for that kind of riding, the frame is quite light in weight. Pitbull then is somehow more urban/big move orientated in terms of handling/feel and construction. Super strong.
It's hard to tell what suits your best, both of them are really nice stock frames that ride differently. Testride the both bikes and make the decision yourself.
Zoo for:
Strong design
Flickable feel
Echo for:
Light feel
Natural handling
more comp orientated.
