I have a mint condition Dynothane Poseidon Force (overseas) and a Track 300C with very low games. They are very nice balls, but I don't find myself using them very much. With that in mind, I'd be willing to trade the pair for something decent of yours in 15lb single drill. I'd have particular interest in a Frantic, Arson Pearl, or something from Motiv, but I'll listen to other offers.
