The spec charts on the 08 Cheetah says 315 to 320fps at 30"draw length but it doesn't come in a 30'draw length. Is there a reason for this or did they just transfer the data from a bengal to the cheetah. And does anyone the the actual speed of an 08 cheetah. I have one with 29"draw 70# shooting a arrow that weighs 435 grain total with a meta peep and 2 string leeches. Any input will be appreciated.
