tuning the set up to your best is key,,
sharp,, shaving sharp,, sometimes a sharpening steel with put the final edge on with ease
put electracal tape on the heads you are not gonna shoot to keep them sharp,,
my friend forgot to take it off and killed large boar with the tape still on,, so not totally necessary but I would advise taking the tape off before shooting at game,,
carry a small file or stone for touch up if you need too,,
a fast flight will add to your set up performance,, every fps you gain,, is like adding a # of draw weight,, something to think about,, would make your set up shoot like a 5 to 7 pound heavier bow,,
keep your silencers to a minimum,,
and shoot the lowest brace you can with perfect arrow flight,, it shoots harder at the lower brace,,
if your arrow is really sharp and you hit right you gonna kill the elk for sure,,
