Arthur, I'm one of those cheapskates!!! Well kinda. I bought my current bow to do EVERYTHING (spots, 3-D, AND HUNTING Alpine Stealth force) At least I'm one of the good cheapskates

useing real hunting equipment for 3-D.
I almost NEVER tell anyone they are shooting too slow or don't have enough KE. What arrows speeds did indians have when shooting Bison?? In reality, most ANY hunting bow has plenty of ability to kill large game quickly and cleanly.
We have all heard the failed expandable stories....what we seem to forget are the failed fixed blade stories...and they are out there as well (Why do we care how tough a Muzzy is....if it's a fixed blade...shouldn't they ALL be tougher than a mech head?).
It has long been a belief that heavy arrows will out penetrate light fast arrows. This simply is NOT always the case. Yeah, If you hit a shoulder it would be nice to blow through it...I TRY not to hit the shoulder (hence the use of a target qualiuty set-up for hunting).
PERSONALLY, I shoot right at the AMO minimum, or below it (Some manufacturors go down to 5 gn/lb). I also use mech heads (but MIGHT pull out my Muzzys....hate to buy new when I have good heads in the box).
TFOX, I might have missed that post...after 4 pages...the screen started to get a bit blurry

Buckskin, I know the article came out sometime last year...Late summer/ early fall....I'll try to find it. It had some REAL good data.
I am not trying to push speed on anyone, but I feel it is incorrect to put blind faith into old wisdom...I like evidence. YES< the old idea of heavy arrows DOES work....all I'm saying is that faster lighter arrows ALSO work.....SOMETIMES better.
