I was recently fitted for AP2 at a local Roger Dunn fitting center (Jim was my fitter, great guy). We were going through various shafts and I ended up liking the Project X 6.0 but I noticed that there was a new shaft that came out relatively recently called Project X LZ. The fitting center did not have that shaft available for me to test but after reading the literature, its seems like it could be compatible for me as well. Will I notice a big difference?
