Weboth agree that KE is not a problem light or heavy with his setup.
And what he really needs is an arrow that ends up where he's aiming.

Why then, would you suggest "rainbowing one in there"????

I completely agree with you on the FOC discussion. It is a fine line to drop some weight but can be done on most setups with a lot of research, simple calculations, and experimenting.

Go Fast - Go Flat - You have plenty of KE and with the smaller surface area you WILL GAIN PENETRATION.

At some point I'm going to sit down with CADD and determine the actual surface area on different diameters AND surface area on different broadheads. I feel this is completely overlooked and a VERY important variable when considering penetration. Like I said - go sink some small, light carbons into the same target, out of the same setup v.s. heavy "logs".

Would love to hear your results - I know what mine have shown(REALITY)
Good luck to all!!!!
