Well all I know is my QX 4Elite Ten Point Crossbow I bought in 2004, shot 316, 315, 316, 317, 316 after the scope was centered at the pro shop I purchased it from. That's good enough for me and I couldn't care any less if there are faster bows or slower bows. Mine shoots like the money I paid for her. I love her dearly. People buy what they want, wheather it's the best or not, they like it enough to buy it. If poor old farts like me worried about energy, drop, and speed, we'd drink some Gerritol, take some vitamins andshift to 3rd gear on our four wheelers.
Anyway, JMO
