The little allen bolt is an interesting addition to the newer versions. I recently got a new one that had the allen bolt.

I've got a coule of older versions that don't have it. <img src="/ubbthreads/images/graemlins/confused.gif" alt="" />

I'm curious how well it will stay in over time with use, and if I'll like it better than the older ones. <img src="/ubbthreads/images/graemlins/blush.gif" alt="" />
