Never drank the carbon kool-aid. I just keep buying them when I find them in the sizes I use so I must be up to about 2K shafts and arrows by now. I can usually choose between two sizes for whatever bow I shoot and prefer the smaller dia and thicker/heavier shafts for my hunting arrows. You cant beat the ease of cutting with a tubing cutter, use hotmelt glue and being able to scrape off old fletching without trashing the shaft. I can also get most bent ones straight enough to keep shooting for practice........YMMV
