70" bow | Arrow Spec — 50lb bow at 32¾" Draw Arrow Spec — 400 Spine (Preferred) Best choice for a newer shooter — stiffer spine is more forgiving of inconsistent release and anchor point while building form. Spec Value Notes Spine 400 Sits at the stiffer end of the 400–500 workable range for ~60lb effective — preferred for form forgiveness Arrow overall length 33" minimum At 32¾" AMO draw, a 32" or shorter arrow does not clear the riser safely at full draw Shaft material Carbon fiber No fiberglass — not rated for this draw weight Shaft inner diameter 6.2mm Standard carbon ID Point weight 125gr preferred / 100gr minimum 125gr pushes total weight to ~459gr, clearing the preferred floor with margin Point type Replaceable screw-in field tip (8-32 thread) Swap for broadheads when hunting capability is needed Fletching 4" shield-cut natural turkey feather Real feather preferred — quieter, better clearance on a longbow shelf Total arrow weight 459gr preferred / 420gr minimum See GPP table below Straightness .006" or better Confirm with seller before buying — not all listings state this Max safe draw weight rating Must cover 60lb minimum Reject any listing rated below 60lb Arrow Spec — 500 Spine (Acceptable Alternative) More commonly available at budget price points. Works at ~60lb effective but sits at the more flexible end of the workable range — less forgiving of form errors than 400 spine. Spec Value Notes Spine 500 Toward the flexible end of the 400–500 workable range — acceptable but not preferred Arrow overall length 33" minimum Same safety requirement as 400 spine Shaft material Carbon fiber No fiberglass Point weight 125gr preferred / 100gr minimum Same weight floor applies regardless of spine Point type Replaceable screw-in field tip (8-32 thread)   Fletching 4" shield-cut natural turkey feather   Total arrow weight 459gr preferred / 420gr minimum Same GPP floor applies Straightness .006" or better Confirm with seller Max safe draw weight rating Must cover 60lb minimum   GPP Reference Table GPP = Grains Per Pound of effective draw weight.
