I am getting on up in years (72) and have a lot of drums. The wife thinks I need to star liquidating to some degree. OK, here is the dilemma: what to keep and what to move. Most of my stuff I don't care to move, but some of it I'm having a really hard time with. I have been collecting Slingerland mid-70s three ply blue glass glitter drums since the early 80s. I have 19 pieces which includes two bop kits and various other sizes and they are all in pristine condition. I also have a five piece USA Custom bop kit, 10,12, 14, 18" bass with matching snare. There is a 120th Anniversary Gretsch bop kit in Champagne sparkle #8 of 120 made and also a red sparkle Catalina Club bop kit. The big question is if I was to keep only one set, which one? I have 20 and 22" bass drums with the Slingerlands, so larger bass drum sets can be thrown into the mix also. Don't just consider bop kits.
