Draw length is a killer. I bought one of those 328 fps Guardians. By the time you put in in my short little arms 27 1/2, throw on some string add ons like whiskers and loops and then shoot a 475 grain arrow,..... well I got it dumbed down to about 260 give or take a couple pounds. MY Darton at the same weight with 50 grain lighter arrows is a tad faster....but not by more than 2 or 3 fps. I suspect that if everyone shot the correct draw length and didn't push the envelope on arrow weight most people would fall in the 235-265 fps in the woods. Speed freaks, well they're their own animal. They got to have the fastest. LOL Long arms make up for a lot.
