For me, saddle is the hardest one... went through a bunch that really didn't work out so good. Body shape, proportions, etc. really make a difference on what works for you. If there's any way you can try before you buy, then do that. Just sitting in it while hanging, even if it's not quite the right size, will tell you a lot that the pictures and opinions can't tell you. The TreeMotion to me was odd, but comfy, but not any more so than some other saddles. I couldn't justify the price, and kept looking. The New Tribe saddles are comfy by nearly anyone's standards, but I couldn't make them work for me, no matter what I did.
So, if you know someone that has a TM, then definately ask them if you can sit in it on a rope and move around a bit. Any saddle, for that matter. They're all too expensive to waste a lot of money and not be happy with it. There's no place near me that I can try them out, but I think Oregon has some brick-and-mortar shops where you might be able to do this. I won't recommend any of them because my own experiences with saddles has been that the ones people rave about I didn't like so much, and some oddball ones I really like. How much of your height is torso and how much is legs seems to really affect how well a given saddle works for you... especially regarding balance point. For me, the New Tribes tried to force me onto my back, no matter how much I adjusted them. For my wife, the New Tribes were perfect. Unfortunately, I climb and she doesn't.
Good luck, and try them all out, if you get the chance. Finding the one that really feels right can be daunting, but makes all the difference in the world when it comes to how much enjoyment you have being in the trees.
