After riding pretty much everything but the pro-climb I would take the Tm1000 over them all, and way before any stocker in the trees (steep tight terrain) The piped m1000's can't even do what I can on my Tm8 at 6lbs. Its all about setup ie clutching and suspension. Twisted just makes more sense, they remove stuff thats not needed and don't add extra problems like some do. Tried and proven. Pretty sure the others have caught up by now and there is a possibility you might be able to gain soemthing from one kit to the next, but what I like is one that works everytime and has the least amount of stuff on it to go wrong, if it ever did. If you like boonedocking you dont need big boost, its just nice to have, I usually run 6-7lbs on my m8 with straight pumpgas and the way I ride more boost will rarely help, I just carry a couple gallons of rg on the back just in case I might want it, haven't used it in 300miles. A pg tm1000 will throttle my tm8 too. The low end power in the trees of the Tm1000is awesome.
