just finished the trial run. i've climbed in a pinnacle, a butterfly 2, own a master 2 deluxe with a rope bridge but nothing i mean nothing is as sweet as a tree motion.... with that said i still have to work a few kinks out.. great saddle, light, and i felt a lot more comfortable on long skinny limb walks. the saddle didn't fall down my butt. it pinched the boys a little but i think i can work that out with a few adjustments, the bridge is a little long... making the friction hitch hard to reach in convoluted contortionistic positions, solution shorten the bridge about 6". it is the best ride i've ridden yet.
