I've got the treemotion and I've had it maybe 2 or 3 years. The whole "10,000 attachment points" really isn't a big selling point in my opinion. How much stuff do you really carry in the tree with you anyhow? For me, if I need something I'll have it sent up. In terms of what I carry every day in the tree, only thing on may accessory loops is a small piece of webbing with a carabiner on it. I used to carry more stuff like dual micropulleys on webbing in case I wanted a redirect, or other widgest but found I use them so rarely it's not worth carrying. I've got a couple buckets overflowing with ascenders, SRT gear, pulleys, rigging, ratchetting pulleys, progress capture pulleys, webbing, spider legs, etc etc etc... If I need something it can be sent up.
The treemotion is "one size fits all" up to 36". I'm 44" and about 250lbs at the moment, 6'3 and it fits me fine. I've replaced the bridge once. To me the big plus are great movement in the bridge, very comfortable all day long harness for fat bastards no matter on spikes or rope only, and no matter if you're hanging a big saw off it. Leg loops very comfortable. Upper D's sit on my hip bones a little and can't be moved, but it isn't noticeable unless I'm non stop full day on spurs. I've never used the lower D's and have no idea what anyone would use them for.
