Not correct of heavier having edge everytime. you'd have to have a huge diff in weight for that statement to be true. A lighter arrow with a FOC in the 19% range can out penetrate a heavier shaft to a point. Also, my 391 gr out penetrate my 520 gr. FOC of 391's in about 18%. FOC of 520's is 11% or so. Weight forward helps penetration too. Also, lighter arrow traveling faster usually always has a higher KE at the same draw weight.

Of course, this stirs the same issue as The physics being fun post in here too.

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.
