Old age and arthritis have taken it's toll and made me appreciate thicker (12.75-13mm) shafts that are easier to handle. What are some of the better performing, not so skinny shafts out there?
If you consider 12.75mm to be thick, what the heck were you playing with before? Both 12.75 and 13mm are current defacto standards for American pool shafts today. Also, LD is more the result of reduced end mass as opposed to a shafts overall diameter. Do a search for more info on LD shafts.
