Replying to The NS Tech Binding Thread

So I have been skiing JJ's with gardians all winter and summer now and have come to realize they are way to heavy for long days/mountaineering. (took that exact setup to the top of rainier) So for this fall i really want to get a tech binding setup going. I have a pair of 192 tst's that i think will make the perfect light weight setup. My question is does anyone on here have any experience with dynafits, or other tech bindings? I ski fairly aggressively so i would like something i can feel confident on. thanks for the advice.
p.s. i don't want beasts because of the strange modifications that must be done to your boots.
