I have always used the info at Pooldawg as a reference when buying a new tip. Great info on that site. But I just wish that suppliers would test a tip prior to sending it out so you don't get that "dud". We have all found inconsistencies within the same brand/category. I just want a tip to hit like the first time a tried one of the original layered moori ms. Man what a heck of feel and grab. Haven't found anything else to match it since.
