probally a x440/3, 1440 or m440 octura, the mac likes the x437/3 too, maybe prop it like a mod OB21. Chris Wood has one of the best running ones I have seen, maybe he can post the faster props.

Chris Wood has one of, if not the fastest 21 whips in the country and if I'm not mistaken he likes a back cut 1440.

Im running a Grimracer 40X52/3 blade on my Whip 21 with a Marty Davis preped Mac 21 for the bullet and the thing flat FLIES!......HOWEVER, my buddy is running an ABC chopper prop and when he is needled right he is 4 to 5 MPH faster than me! Marty is working on the same prop for me, and hopefully i will pick up even more speed, but the Grimracer prop does work GREAT also!
