Replying to What bindings for Alpine Touring?

I know it's been talked about a lot, but I'm doing it again. Scratch the obvious argument about backcountry risk assessment and safety skills for the time being......

I'm mostly looking for the right binding. I'm probably going to be using my 184 Blogs from last year--I'm 5'6 135lbs and I've got a pair of dalbello kryptons from a few years ago. I'd say that I ski rather aggressively.

First: are the dynafits only for use with dynafit boots? If not, are they a plausible option for backcountry/sidecountry adventures as well as normal inbounds skiing? (we've all heard eric hjorleifson slays them, but I'm kind of skeptical).

Second option: the blackdiamond fritschi diamirs. Same question as above. To me, these seem like a pretty good options--your thoughts?

Third: Dukes are heavy, but I'm probably a good fit for griffons, no? Overall thoughts on these would be helpful.

I'm not going with the Trekkers. I've saved up some money and my roommate had the trekkers for two uses before they broke so I wanna make a good investment for a good price.

Finally: I'm not doing any serious backcountry expeditions and I'm probably not going to get out into the backcountry more than once a week. With this in mind, one would probably recommend the trekkers, but once again I'm not buying something that's gonna break so easily--what's the best overall binding for what I've said about myself?

Thanks in Advance!
