I just got a bunch of tempered nickel in from SV, so I think the B-Deck will be the first to test out TC on the M-ClassWow, my first order took 15 days and my second order, which was the bell cap, took about 9 days. So holy shipping that's fast for C9V.
Can't wait to hear your thoughts on the B deck.....and the bell cap. You using Kanthal or nickel with your SqR?
