McDermott i3 11.75mm. I`m still adjusting from a 12.5mm shaft.
I`m using a closed bridge and i think a 11.75mm shaft is pushing the limits of how small a loop i can make with my fingers.

I've noticed that if I start struggling while using an 11.75mm, then I can pull out the 12.75 and shoot the lights out. More of a mental thing I guess. Sometime I'll switch down with similar results. I alternate 3 playing cues regularly too.
