I have an OB1 and prefer it much more than the 314^2. I also have a Z2 and I like it, but I'm wondering if I would like the OB2 more since I love the OB1. I have never hit an OB2 and don't know anyone who has one. Are they to close to justify having both? I really wish there were a LD shaft between the two in diameter at about 12mm or 12.25mm
