Well it's pretty obvious I like heavy.. My hunting arrows are over 540 gns.. They have always worked for me and the only reason I could think of using a lighter and faster arrow is because someone can't judge distance!
What would you rather drop on your foot from four feet up, a baseball or a bowling ball?... Some guys think that shooting 125 grains is heavy.. that's funny to me, I don't like ANY broad head under 220 grains.. like I said, it works for me, I hit a big buck several years ago a little high at 45 yards, it completly knocked him off his feet, you could see him going backwards, and when he hit all four legs were straight up in the air... No way I would ever go back to shooting light for speed, those that have talked into trying it, are still shooting heavy.
But Dance with the one that Brung ya!!! What you trust is what you should shoot!
