Hi, I would suggest the monty 221ti or the 221pr, Or the new echo lite. This is because my friend has recently purchased a monty 221pr and i find it really easy to sidehop, bunnyhop and throw around where i want it. I would suggest it for competition use because it was designed for competing in natural events and it feels really responsive and easy to throw around compared to other bikes i have ridden. I would also suggest the echo lite 2008 because the reviews on them seem good and in my opinion it is a frame with good looks aswell as a frame that looks strong. Both the Echo and both the montys come in rear disk versions and i would highly reccomend both of the frames. Cheers. Sam
