Oh, I wasn't saying that a piston gun doesn't get dirty, just the cam area doesn't get as dirty, so lube there wouldn't get dirty quick. I also agree that I'm getting less enchanted with the couple of pistons that I'm playing with, although the experimentation was fun. I'm currently building only DI guns, as I agree with all the arguments given above. I suspected that even before I built the piston guns, but it's still fun to find out. I've never had a failure in a DI gun from being dirty either.
