I've enjoyed following this thread for the info - still on the fence about the VB.
I was re-reading some of the thread this morning and noticed a in the OP's OP he says off-handedly that he couldn't remember who made his VB (later recalls it to be from
Zpacks). I thought this was funny, but probably not that funny. I could never get new gear without knowing all about it. Props to the OP for being a real outdoorsman and using his gear more than knowing his brands
