I have always succesfully used Tru Turn spinners and think they are of the highest quality but from what I have seen the Dave Brown Spinners look to be a good value. I actually purchased one of their 3 1/2" Ultimate spinners at the Wram Show yesterday and am pretty impressed. I do believe that both Tru Turn and Dave Brown will custom cut the spinners to fit Menz, etc. props. They are both great companies to deal with. In fact, I think some of the mail order companies are now selling Tru Turns with a Menz cut.
As far as the adapter, I am a BME guy so can not help you. Maybe someone else can chime in with the appropriate adapter. In short, your best bet would be to contact Tru Turn or Dave Brown direct as they will have the exact info you need. cbk
