I knew you knew what you were talking about. I just wanted to make it clear for him. So "technically", you CANT have it "reconed" to a 12, but you can have a 15 made into a 12.
technically it can't be reconed, because that just means putting the same size cone back on. but the motors are usually the same for all sizes. so yeah, with a new basket it can be made into a 12.
