    Assuming old style pump, Concord 12/18. I've seen a dynafly on an old style pump work pretty damn good too, but you need to keep the pitch DOWN, to keep the rpms UP in closed course. The dynafly isn't a great prop to pitch on the beach and hope to keep the edges from either pulling away or scrubbing the liner. The concord is way more forgiving that way, and dirt cheap these days. Combined with a Pro-shoe/Grate setup, and drop your tabs 2 washers with a stock rideplate, and you'll do okay in the rough stuff. It will be dirt-slow in testing on smooth water.

    13/19 Swirl (Not concord) might be good as well-especially running the bigger 87mm exit nozzle-might need a bit of tweaking, but not much.

    things to consider.

    If you are a racer riding Nothing other than a skat-trak swirl prop you are missing out. Speaking S a former gpr racer my self.
    Set up has to be considered
    Pump condition, wear ring and bearings in the pump as well.
    What class are you running ? What are your mods? Have a good tach stock ones are difficult to read and are inaccuraTe. Well rider size and weight too.
