I ride the Zoo CLS Python '05, and love it (Y) It rides well on natural and can transfer(wheel swap) on higher stuff, which is always nice ;)
The Echo Team(long) rides fairly similar to the Python, in whichit sidehops well, and is fairly long, but is a bit flickier. :) I think the '04 Team has similar geometry?
The Monty 221 wont last long if you ride street on it( like big drop gaps, big drops) and its a bit expensive. It'll ride fairly nice on rocks, because its short wheel base, but long cock-pit area :D
The Koxx Levelboss has similar geometry to a Onza T-pro, but theyre still just as weak.
The Koxx XTP is another natural orientated bike, due to its light weight, and flicky rear end. But it wont last doing drop gaps and generally going big on stuff.
I think he means the headtube :o
