I have used Talisman tips for several years. Two WB Hard and one Pro Hard. The Pro Hard tip is great. The WB Hard is my favorite commercial tip. But that may only be because I have more experience with their WB tips. Both are accurate and put plenty of action on the cue ball. None of the tips are showing signs of wear. So I may not need too many more.
I have not had problems with delamination, but have heard of the issues that others experienced. With only three samples for making judgements, I cannot help decide if anything has improved. No signs of mushrooming.
I use a Talisman Extra Hard as a break tip. Also a great tip.
