I started with Phenolic on a McDermott Sledgehammer and wasn't a big fan so I changed.
I went to the Bulletproof and installed it on probably 6 cues. Most everyone loved it except the jumpers. I liked mine at first but after while, lost my passion for it. While I consistently made 3-4 balls on the break, I didn't get the 8_ball snap that I used to get and as I used it more and more, it got increasingly difficult to hold chalk unless I scuffed the tip first.
I then had a Black Pearl Jump/Break cue built for me by Al Bautista. It came with a white diamond tip. Total miscue machine. I took the tip off after two days. I replaced it with a Bulletproof (largely because I had one on hand). Same miscue problem.
This week is tried two new approaches:
I put a Samsara on my Black Pearl. Rock hard and has the "ting" sound but performs well.
The star of the week for me is Kamui's latest release, the "Sai Control Break" tip. I put it on my Sledgehammer and am very impressed. I made 4 balls on the break three times last night in 9 ball league. This tip also comes with a dimple pattern on the glue side so I chose no sanding and it held great and shaped easily.
My breaks have never been better. Kamui Sai Control Break is the best tip I've ever installed or played with. Forget your Kamui pre-conceptions to date and give this tip a chance. It may be the best break tip on the market today. I ordered 5 more of them today. Now I just have to get rid of the Zan's, Samsara's, Bullletproofs, White Diamonds Phenolics, etc. that I've accumulated...
