Either the echo or the lynx IMO, never heard bad things about either, lynx for strength but echo for a really smooth, nice ride
You know you loved my echo...
EDIT: Pros/cons of :
Onza blade/comp: everyone liks them for some reason, IMO rides horrid (the comp that is). another con: its an onza
Echo lite: very very very nice riding frame, very light and looks really nice, dont no any cons to be honest!
Zoo lynx: out of the ones i have tried i didnt like the ride, might have just been the parts/tyre pressures etc, heard they are extremly strong... this and the echo should be your choices.
Because simple: Never rode one... now that barry's one is gone i prob never will! Quite nice though
Monty: i dont even know what it looks like lol
