McDermott has a new G-Force shaft that is now standard on their cues $400 and up; or you can pick up just the shaft for $150. I'm finding myself very attracted to it....
And while we're at it - any good reviews for the I shafts?
It's actually G-core, good thread on it here: http://forums.azbilliards.com/showthread.php?t=132372&highlight=mcdermott. Seems like quite the nice shaft to come stock on a cue really. I have a cue coming from McD in the next week or two that will have one of these on it so I'm looking forward to giving it a try.
