I have used the Bohnning Classic for years, and didn't notice any problems using a Bitz to fletch? Before that I shot nothing but Mercury nocks, and only swapped because the quality went down the crapper.
Currently I'm switching back to Mercury nocks--I got a deal I couldn't refuseon some "off" colors (brown, green, blue, grey, tan)--they are the old ones too. Got near 7,000 Mercs to use up before I swap to anything else--should last me a season or two at least.
