RE: arrow specs....?
Every arrow manufacturer makes different qualities of arrows. They are sorted out by weight and straightness tolerances. The tighter the tolerances, the more expensive the arrow. To determine if an arrow is ok for a given bow, you need to be cognicent of the spine. This is the deflection, or how much the arrow bends upon release. All rate their spine different, but most companies rate in inches. I shoot 340's, or, in other words, the spine deflection is .340 inches. Correct spine is determined by cam type and maxiumum draw weight. www.easton.com has a program you can download to determine what spine to use. Easton rates their spine in the aforementioned fashion. Others use, say, 5575, or 4560, ect. The theory here is the 5570 is good for a bow with draw weights between 55 and 70 pounds. Not every arrow is good for every bow. Hope this helps.
