My fave was the zoot and the adamant a1. The czar wasnt the nicest frame to run always feels like you were gonna fall over the front of the bike. The zoot was really nice to ride a nice blend of trials geo without moving to far away from a street geo. The only thing i will say about onza zoots are that they are a bit of a tank in the 24 area of frames. The DOBs were lush bike to ride never cracked eney of them the only thing i hated about them was the frist one had the upside down magura mounts and was a pain to get the allen key in place to tightin the bolts up and they get really flexy in the rear end after a while. The planet x and the rulong were double disc. The planet x had climb 8 6 pot discs and one day later they went straight in the bin the rulong had a hope brake on the back and that was on hell of a brake stopped me no matter what i did. Hope that helps a little Cheers, Biddle
