Myself and some others talked about the Temets a bit in this post: http://www.wakeworld.com/MB/Discus/messages/1/101454.html?1079480499
Basically...I like the top BOA...it really grabs the area around your lower shin/upper ankle. If you crank down on the option 2 strap your heel won't budge a bit. I couldnt get the laces over the toes quite as tight as I would have liked, but overall I like the bindings a lot. It's kind of a pain to get into because you have to pull the laces tight, then crank downt he BOA, then fix the strap.
fyi...i demo'd the Temets for 2 days...I normally ride 03 Byerly's like you (I was demo-ing temets because my Byerlys were gettin warranty work done, go figure)
I don't think the Temets will hold up any better than the Byerly's...Temets appear to have some week points where I think the stitching will start to come undone like the Byerly's.
I was trying an S-bend and took a nasty fall...My right foot came like half way out of the binding and it tweaked my foot/ankle a little. I think if I would have had my Byerly's on my foot would have popped out and I would have been ok, but the Temets held me a lot more at the heel and upper ankle so it only let my foot come half way out which was bad.
Not that I want my feet popping out of bindigns, but when you take a really hard fall I'd rather have my feet come out and twist up my ankles.
