Jiffer, I'm in the same boat you are. My first premium strap lasted maybe 6 weeks. I'm now on my 2nd and in watchful waiting mode. I do not want to use the stiff version. However, I know people who use the premium strap and have not had a problem.

Fortunately, I bought my first one from REI using my dividend and they keep them in stock so I can exchange as necessary. Sigh.
