Just wanted to give a shout out for Kumui tips. I know there is a lot of scuttlebutt about the chalk...25 and up for a piece LOL! However the tips are worth the money! I had Andy Gilbert put on Kumui Black Hard and I use blue diamond chalk...I have not had a single miscue and the tip has yet to mushroom or lose its shape at all! I don't know if it is just in my head or not but there are a few "twister" banks (one-pocket) that I can make pretty regularly with this tip that I cannot make with my other ones...so if you are on the fence about the tips, they are well worth the price and it would seem they actually hold up longer than others while letting you apply more english! Thanks.
