I have 3 McDermotts, linnen wrap, leather wrap, and no wrap, all with 12.75 gcore shafts. Their nice cues, but honestly play mostly with my Schons, and my DZ. The gcore shaft is not bad, but the only negative thing I have to say about all 3 of my Mcdermotts, is they are more rear balanced than my Schons, and I lake a more forward balanced cue. My Schons run between 18 7/8" - 19 1/4", and the Mcdermotts run about a inch less than that. I am looking at getting a 30" Jacoby Ultra shaft for my Mcdermotts, like I have for my Schons, and will probably use them more after that as the shaft I am looking at is also .2 oz heavier than the gcore and that will allow me to take a little weight off the weight bolt on the McDermott wrap less cue I want to use. All in all they are really nice cues, just not quite the weight balance of what I am used to, but hopefully that will change with the new shaft I am getting.
