I think I will be in the minority here.
My total finished arrow weight with a 100-grain broadhead is 565-grains.
I am shooting this arrow out of a 2006 BowTech Tribute, with a 30"-draw @ 72-pounds.

I shoot a heavy arrow for three reasons.
1)I hunt elk & mule deer, in my mind heavy is better for bigger game.
2)Better accuracy.
3) Less noise.

Whatis my KE? I don'thave a clue how youadded the numbers up and come up withmy KE?

Thanks & Good luck hunting,

WK
