If anyone is looking for good black linen phenolic there is a new source. David Warther now has it for sale as well as some other good materials. I was able to get several samples of this phenolic rod and I am very pleased with it. It machines nice, is not pitted, finishes nice, and is very black. He calls it Jet-Phen® black phenolic. I have used the samples in a cue and will continue using it.
