OP/TECH USA1001062 Super Classic Strap - Uni Loop (Black)

How do the release buckles hold up? If that thing breaks, the strap will fall off shoulders and you just broke a very expensive $1k-$3k camera...

I'm confused on the Pattern selection? Does the "single' come with the pieces needed to attach it to my camera or do i select strap+uni loop?

I am looking for a strap to increase comfort and camera safety during travel touring. Is this the most suitable OpTech strap for my needs?

I have a Sony NEX 5N. Would this strap be too big for Sony NEX cameras?
