I have recently starting using a 30" shaft (Predator 2) on a butt with a Radial pin. Do OB-1 shafts for Radials come in a 30" length? I saw one source with a 30" OB-1 partial, so I guess I could get one and have a cue maker set it up for a Radial pin, but I just wondered if I can get a 30" version already made for a Radial.
