This is up for discussion again in the cuemaker's section and I thought I'd post it here for those that don't go there very often. I've listened to it several times, it's 16 of the finest cuemakers in the world talking about cuemaking for over an hour and a half. Topics include playability vs. design, low deflection shafts, costs, best playing cues, and much more. This is a really informative discussion.
