Hey Cary, I switched to the TM because, frankly, after trying it out at a competition, I was in love. The way the bridge supports you, no matter which way u turn, is amazing. I also liked how I could change the length of my bridge fairly easily. To me, the back pad feels better in some situations also.
When I bought my TM, I was on the fence between buying the TM or the SRT Sequoia. I had heard some great things about it, and since I was getting into SRT and upgrading, it was a toss up between it and the TM. But like I said, after trying it out at a competition, I knew the TM would be the better of the two.
Now that I've had ample time to climb in it, and from my experience with the Sequoia, I'd have to say they are pretty darn close to equals. The TM has a few better points, but the same could be said for the SRT Sequoia. I think when it comes time to replace my TM or whatever, the Sequoia SRT will be my first choice, simply because I'm going to try and do SRT only from now on.
