Any idea what years the green logo was used. I've never had one with this 5/16 14"flat faced . I was thinkin about converting to 3/8 10 but th I s cue with this joint hits the ball as good as any cue ive had & I've had hundreds of cues over the years . Think I'll just put some collars & maybe hoppe ring & keep the same joint. Was there many made with this pin as opposed to the glider joint?
