arrow weight/f.p.s

[Jotis]

Is it worth changing arrows/components over 20 grains? I am looking to gain a few more f.p.s

You will gain around 7 fps.

It's not uncommon for me to have 125 and 100 gr heads on arrows while I'm hunting. At 40 I add a yard.

The first question is - Where are you now?

To me, 20 grains isn't worth the effort in itself. But if you were to combine that with something like adding 5# of draw weight or a faster bow then it's measurable.

I made an arrow speed calculator the other day for people to play around with. It's based on a good sized dataset with actual chronograph data at varying lengths and weights. I find it a little more accurate than others out there, but none are perfect. This one lets you detune the IBO so it's closer to reality. Most bows I find are about 5% lower than advertised.

What does that extra few fps get you?
