The new Infinite Edge adjusts from 5 lbs. up to 70 lbs. of draw weight, and from 13" to 30" of draw length. Seriously! No parts exchanges or special tools required. You don't even need a bow press. With just two little wrenches, the Infinite Edge can be adjusted from top to bottom - for any purpose - to fit practically any shooter.
sling 一定要。拉弓和释放时,弓把不能握着,得推。释放后弓往前弹,sling就拉住它。see in videos of recurve bow match (eg Olympics), the bow would kind of drop forward after release (arrow flies out) - that's because of the stabilizer's weight and that the bow goes loose between archer's hand and sling. Same thing for compound (or at least I think so - haven't had much experience with compound yet), though the slings for recurve and compound are different.

For example, if you order your bow set for 60# and 28" draw length, your arrows are likely to be 400 spine shafts trimmed roughly 27-28" long
