Looking to acquire my first Kaywoodie, I would like to increase my chances of landing a good one. Is a 2 digit coded Kaywoodie with 3 or 4 hole stinger always going to be inferior to an early 4 Digit pipe? How do you know which pipe(s) to avoid from an age/model number pov? If at all? I know on any given day, a pipe might be a great smoker while others of the same type suck. But there has to be good criteria to lead in the best direction. Yes?
