I ordered mine from Dave (Jacoby) at last years DCC. He had a prototype that I tried, and was SOLD on it after about 10 minutes. I like the feel of it better than the 314-2 and the OB1 - It falls in between the two (not too soft/mushy, and no annoying DONK when you hit it). So, after about a full year with it....I couldn't be happier.
BTW, it is TOTALLY custom - you could order it in Z or OB2 size (11.75mm), or maybe even smaller up to (I think) 13.5mm, and any size in between....:thumbup:
