I get 2 blades to fly just fine. But am running higher FOC.
Also never popped em over 280 FPS
Everything gets 4" helical feathers w decent offset too
I run 75gr brass inserts and I believe the lightest arrow shaft I hunt with is at 11gr per inch. Like I said I am sure someone will come along and say that 2 blades fly fine. Fine is subjective, and I can get them to fly fine too. But you, me, or anyone else isn't getting them to fly better than three or four blade. Simple as physics and you can't change physics. But fine is good to go for some people. I prefer to get my setup as close to perfection as I can. If a two blade design held an advantage over three and four blade designs they would be selling a lot more two blade over three and four blades.
