I've been using multiple 2-stage B&A for a few years now and between those and the Geissele super 700, they're at the top of my list. I've sent Calvin Elites, Jewells, etc. down the road since buying my first Bix. The TT primary is nice but I actually prefer the older Timney 510 or the tuned up Walker I have. If I were searching for a great single stage now, I'd agree the TT Diamond is where its at. The one I used was outstanding.
