It seems I have fake kamuis.... they don´t last 2 months, I have a Black S on my playing cue and It´s driving me crazy. It became really hard and I miscue a lot with it, I used the gator grip, 80 grit sand paper and nothing seems to work. Some in here will say it´s the stroke, but I practiced full table length draw with my break cue (Phenolic) and no miscues at all, this kamuis are being a pain in the neck.
The brown ones feels better, but they mushroom a lot too. Maybe I´m getting fake kamuis..........
Wow, makes me wonder if I just got lucky with the few I have bought. If I spent 20 dollars on a tip I expect it to be not only good but one of the best tips out there.
