propeller choice?

[FatCub300]

I kinda wish I built a new IO 360 but I built a IO 375 ha, it is counter weighted but I am still hearing concerns about pulse energy? I'd love to bolt on a McCauly 82/42 I like the kiss system ! But they say they have done no testing on this combo. It is experimental so I could just bolt it on and go? Maybe I am overthinking this

My 4 place has a Continental IO-520D without the injection, carburetor instead like the P-Ponk engines

10/4 I am only running 9:1 comp but with electronic ignition so it will be pretty crisp what WW prop are you running ?

200A. The “legacy” Whirl Wind Aviation version. Great prop. As light as a CS prop can be, great thrust, and a little twist near the hub to promote cooling and ram air.
