If you are talkiing about the TAOM No problem there, what I did see is like every leather tip I have ever used is after 2 months the tip was starting to get harder already, If you are talking about the Bulletproof then No as well, I had shaped my tip to a dime radius because "it looked better to me" and I did have problems with miscues, my shaft size is 12.0 mm and I learned a nickel radius allows you to go lower on the cueball with that shaft size, so I shaped my tip to a nickel radius and it looked terrible to me but I could go way lower and further out on the cueball than I could have imagined, I also learned this tip holds chalk better than any tip I have ever owned, I use TAOM V10 chalk and you don't need to chalk after every shot, I use a Tip pik type tool about every 2 weeks and I practice a minimum of an hour a day plus play in league, this is my experience, hope it helps.
