I started shooting trad bows a little less than 2 years ago because I wanted something simplier. However, being an enginer, I soon found myself reading WAY TOO much (and second guessing about a half dozen bows I went through, along with a multitude of arrows of different weights and broadheads)until one day a buddy of mine said "Fred, it's just two sticks and a string, sharpen that broadhead and GO HUNT!"
Not taking anything from Mr. Ashby, but it doesn't take "Ashby stats" to produce a kill on basically anything that walks North America.
Go have fun and quit worrying .... 9 gpp on up, and mid 160 fps (even slower is OK) and I think you have a lethal weapon that I promise if you do your part, it will do its part.
