I think shooting a 430-475G arrow at 270+fps is a good happy medium especially with thinner arrows like the 4 or 5mm FMJs or Axis. This should allow for use of bigger mechanical broadheads without worry about not getting pass throughs. It’s about the best I can get with a 27 1/2” DL bow anyway although I’d love to see better speeds but without compromising the draw cycle and hold weight. I’ve had bad luck with large 3 blade reapers (whitetail specials) on a 60lb draw bow that wasn’t as fast (think I was barely hitting 260fps). I shoot heavier draw weight now but still stay away for huge 3 blade mechanicals due to potential pass through issues. The G5 deadmeats are the the biggest I’ll go for a compound but typically shoot rage trypans and have had good luck with those. So, in short, I think you need to decide on what broadhead you will shoot and match your arrow to it along with your bow speed
390 Grain Easton Sonic 6.0 Match Grade. Going 310FPS at 72lbs 29 inches. Grim Reaper Whitetail Special. Might be unpopular set up but I’ve had success with it. I love tight pin gaps and a very flat shooting arrow.
I've always shot the heaviest arrow I can get to 280 fps. For me, this is 440-450 gr. That's my all-around arrow.
For midwest whitetail specific, I may shed some weight and go faster next year with the new Easton 5.0. Im thinking maybe 415 gr around 290 fps.
For these Kansas whitetails, a smaller gap 2-pin would be desirable as long as I keep my arrow over 400 gr. I started at around 380 gr at 305 fps. In hindsight, that was a pretty sweet set-up, just not a lot of passthroughs. (I think shot angle makes a bigger difference though.)
