I just bought a GBB 5 wood, used, from Golfsmith. Looking on the Callaway website for settings and looks like the inner ring (next to head) is Bias and outer ring is loft. The bias instruction doesn't mention what the +1 is used for and the loft instruction doesn't list what the N is used for. Loft options just lists S, +1, +2, -1 and Lie options just lists N, and D.
What am I missing?
