Pete Williams & his service is the same irrespective of the size of the purchase which is great as most firms are ALL about the money ! I have just purchased Molinari chalk & coupled with my Kamui tip the difference is amazing. The chalk adheres on a single pass across the tip & the grip imparted is excellent makes Masters chalk ( which I have used for 50 odd years! ) redundant. I love it. Pete emailed me back quickly when I asked what it was like with his view. Coupled with the weekly newsletter which always has good topics & reply is encouraged, whats not to like ?Thanks regards Andrew
