Huge hands and height can affect what works best for you. I draw and spin just fine w my war clubs. 14mm.I played with a guy came from the straight pool heyday. Played with a Richard Black cue. 14 mm shafts late 80's early 90's. He played real good. Owned a pool hall that held 14.1 US open qualifiers in the 70's. Never hit the ball hard and still got around the table. He lightly sanded shafts. Had 4 of them. When his player shaft got down, he'd order another for the rotation. Shafts were like tree trunks to me. I used to ask him if I could have the old ones for my wood stove. I guess it's all in the beholder.
Almost like one of those big ol house cues.
