NO! That is so wrong! The only time that could possibly happen is if you use an arrow so heavy it's outside the bow's efficiency range. And that's got to beINSANELY heavy.

As long as you're talking about using the same bow at the same draw weight, with arrows running about 12 grains per poundor less,a lighter, faster arrow is NEVER going to have more KE than a heavier one.

I suggest getting a few copies of "Bowhunting World Magazine" and read some of Norb Mullaney's bow reports. He does a great job of charting KE and efficiency with arrows ranging from light to heavy.

Sorry, LittleChief, but you were being told falsehood and I had to correct it. Your setup is fine.
