Ahhhh never mind I actually found the error of my calculation after I wrote it out.....[8D]

It actually is not as bad as it came out the first time ..lol

See some times just posting all this info down on paper instead of doing it in your head helps a ton

See In that calculation I didnt allow the drop in speed switching to the Heavier A/C Slim, thus in a perfect world shooting an arrow at the exact speed it would be a larger diffrence because you are moving more mass at a faster speed.
