Here on the gulf coast humidity is a way of life. I don't use any powder. I use very fine 1500 sand paper or leather. Also keeping your hands clean helps as well. I find when the fingers get all blue from the chalk, washing with soap/water or hand sanitizer makes the cue glide through the fingers with no issues. With all this said, we play indoors with the AC turned down COLD here. No way I'm going to pay to play and sweat. If I want to sweat, I'll go to the gym.
If powder could keep me from delivering the cue where I didn't want to, I'd be buying stock in it, as well as using it by the case.:smile:
The last time I went to the hall, the box that contained the balls looked like someone had a baby powder fest in it. It was literally about 1/8 an inch thick on every ball in the box. I'm glad I didn't see the table they were playing on. It probably looked like they had been making break on that sucker.
