Yeah, for awhile I've been obsessing over how to get the very newest build, but I'm starting to think it doesn't matter. Exchange it enough times and hopefully you'll get one you're satisfied with or at least can live with. Then, be sure you don't drop it.
I'm on the fence on returning my current 11/6. It's got a gap between the two halves that none of my other ones have, but at least it doesn't randomly die on me.
