The toms from this era had flat bearing edges as you found out and aren't that great sounding. I am a fairly staunch purist, so I would hate to see you re cut the bearing edges. but if you do I would cut them to 30 degrees roundover. your gonna have a hard time finding the floor tom for this kit.
Yeah, I am not crazy about recutting the edges. Not sure what I will do. I want to put them to use for sure on both recording sessions and the occasional live gig. They are too cool to keep in the closet. I will keep an eye peeled for the floor tom. It came with a 20x20 radio king floor in white marine pearl. I will just use that for a while until the other one pops up. Thanks for the info.
