As I said earlier in the thread, I used Kamui Clear Black mediums for about 10 years (~2014 - ~2024). During that time I had at least 5 Kamui tips on at least 2 shafts. It was likely more, but that's what I remember for sure. The shafts I remember for sure are a McDermott i-2 and a Predator Revo 12.9. I might still have the Kamui on the i-2, I'd have to look.
The last two or three tips I had glazed over enough that I generally had to scuff my tip at least every other time I played. I don't remember enough about the earlier 2 in order to gauge timeframe, but on the last one, it was within a couple months for sure. At that point, I was using Kamui Roku or Taom V10 chalk whereas earlier on, I used Master chalk exclusively (probably for the first 3 tips). While using Master, I don't remember the same issue being a problem, but it could have been.
The Kamui/Taom chalk did its job well enough, but I'd have to reapply every few shots. In the last 3 years or so and with the tips that I have used more recently, I can play a full rack at a minimum without needing to chalk again.
I've used Whitten, Zan Hybrid Max, and Taom Fusion tips in the last 3 years with Kamui Roku without seeing a similar issue with glazing. I scuff maybe once a month playing 3-4 days a week.
