Haha, 916s aren't the most durable binding out there... The wings and the AFD(I think it's called, the part the bottom of your toe is on) have small important pieces come off all the time, not to mention Sollys brakes breaking the most of any binding company out there. I love them, but just because they're almost all metal and weigh 6.4lbs doesn't mean they're the most durable.
And yes, cheap Tyrolias suck horribly, as bad as low end Sollys, and I wouldn't ever touch a Marker binding other than Dukes, or low end Looks(so to sum up all binding brands have shitty bindings).
Tyrolia Peak 15s and 18s are great, way more durable(different materials) than some past or lower end Tyrolias(including Peak 12s), and don't pre release. I've owned FKS 155s, Marker M series, Dukes, Solly 916s, S914s, 914 Labs, Tyrolia Peak 15s, Tyrolia Peak 18s, Tyrolia FF12s and a few others, and like the GOOD Tyrolias the best. They feel best edge to edge and I can ski them at a lower din than any other brand of bindings(I found that the FKS heel pre-released at the same din that Tyrolias didn't, and Tyrolias still did come off when they should). Dukes don't compare to the better bindings I named and neither do Jesters, which is why I put them at the bottom of my list, and the only reason I own a pair(on my 202 Lotuses) is so I can tour decently(takes Trekkers off the list of options) and ski real hard(takes other AT bindings off the list). I simply didn't like the feel of non-FKS Looks(and Jesters) but they do alright and lots of people love them.
