RE: What grain broadhead should I shoot?
 

Just ran your specs through the program. I'm showing good spine at a 60 pound draw weight and using 100 grain tips. However, your FOC is lacking, yours is 7.5%. Nothing you can really do about that. You really need to have the 340's to have that "perfect arrow."

I'm assuming you have the 60/70 pound limbs since you're at 64 pounds? Some 50/60 bows (maxed out) can be 4 or so pounds over.

I'm shooting a Switchback at 70 lbs with Easton axis 400s as well. My draw is around 30.5". The muzzy 3 blade 100 gr work great for me. Just ask the doe I smoked this past saturday!:D

RE: What grain broadhead should I shoot?
 

The broadhead seemed straight and on spin test.I shot 2 muzzy 100 s and 2 muzzy 125s changed up arrows and everything.Shot a slick trick 100 and it flew well out of several arrows.But I havent used slick tricks and dont know what it can do to a deer.Experienced muzzys and luv em but with Beman 400 is what I shot muzzy 100 with.
