Waz I find with with most Tomo shapes Quad is the go because they are so wide in the tail. The problem you have with your Minion as a Thruster is the rear centre box is a shallow one. You will need a Large centre twin foiled rear with the short base. Unfortunately they don't make them. I getting some moulds made so my V6 & V8 will fit but thats 8 weeks away. I have had heaps of request for it. Simon put the shallow rear box in for nubsters.
If you want to test it out just get an old rear centre fin (USA box) and trace out the short future base and grind away give that a try.
