of course vermon nailed it. I have a pair of KAP Challenger Carbons short 32#. On my 14" Morrison they give me 45#@28". I have a AMO 28" draw. Mr Average. I been shooting it a BH of 7&1/4". I built a TS1 string and left the fuzzy ends on the loop braid, out string jacks at 1/4, 1/2. I put limbs savers on the limbs. I got a nice little "thunk" on release.
with redline 520 cut 29" i am getting low 190fps which is good for my draw lenght.
Most of the ilf limbs I have tried on the riser gsve me from 10 to 12 pounds over legend draw wieghts.
hope this helps
btw - if you try other ilf limbs than Morrison, don't force them in and check to see that the butt end of the limb is not force against the end of the riser pocket. I gotta try before you buy. since the morrison is a key hole attachment, they have to be cut for a specific ilf fitting. not all ilf fittings are the same by a long shot.
