"So a 40lb bow is more efficeint and has a higher KE with a 700 gr. arrow than it than it would be with a 300 gr. arrow"

I suggest you go back and read a few more posts before trying to put words in my mouth again, Silentassassin. That has already been dealt with.

The point with heavy arrows is NOT KE. It is momentum. I posted this in response to TFOX w-a-y back there before you joined the discussion:

"I could use a 400 grain arrow and still get the same amount of momentum as I get with my 2315's @ 220 fps but I'd have to jack that 400 grainer up to around 340 fps for some 103 ft lbs of energy to do it."

You gain momentum at a heckuvalot faster rate than KE with weight.

Within typical bowhunting yardages of 30 yards and less, I don't see an inch or so flatter trajectory to be enough of a benefit to shoot much more speed than what I'm shooting now. Certainly not enough to drop any energy or momentum from what I'm getting or submitting my bow to the extra strain of shooting light arrows.
