I own tyrolia peak 15's (same binding as this) and tied with FKS 18's, these are the only bindings I've used that I haven't had any problems with. No prerelease... Nothing. I have them on some 181 pipecleaners and they have held up incredibly well after 100+ days of use. I have no complaints, and the din range of the 15 is arguably the most versatile. I plan on sticking to these and FKS from now on. Great bindings.
