My Fedora Xcellerator is 48@30. I shoot a 503 grain arrow at 175 FPS. I think any bow shooting around 10 grains per inch of draw over 180 FPS is pretty exceptional ... just my opinion. True, heavy weight, high FOC ... etc beats fast and light for sure. I guess heavy and fast is pretty good too, as long as you hit were you aim, and for me personally, slower has always been more forgiving. However, I am very pleased with my Fedora, it has good speed, and is super quiet. Best of all I shoot it pretty well. My Dwyers are slower, but they go were you put them too.
