I have started to look at purchasing a Hoyt Ultra Elite, P.S.E. Mach Pro with NRG single cam, AR 37 Blade with Ram Cam and a half. Shooting 60 lb., 28" draw using 5 gr. per pound. I would like to shoot around 270 fps or better! Which of these do you think would do that an if they all will do that which one should I go with and why? May use the same bow lowered to 50-53 lbs. to shoot indoors for spot shooting. Thanks
