Okay, Matt. A little recomputation based on your findings...

The heavier arrow will hit 22/1,000ths of a second later and maybe hit 3/32" lower.

You' re right! It don' t amount to a hill o' beans!

Thanks for the info though. Interesting. I knew ' they' were specifically designing cams to fling lighter arrows more efficiently, but didn' t realize they' re ruining efficiency with heavier arrows at the same time![][:' (]

Coug, also look at the carbon/glass composite arrows. I' ve become especially fond of some Carbon Express Terminator Selects that JeffB sent me. In size 6075, they run 10.7 grains per inch for the black, and 12 grains per inch for the camo Hunters. Quite reasonably priced as well.

LOL, Matt, you were posting whilst I was typing. Ya beat me to the recommendation on the Terminators.
