I have some Shawnees with the foam/carbon longbow limbs, some Cheyennes with boo recurve limbs and some with foam recurve limbs, and an ILF with the foam/carbon longbow limbs. I like all of them, but prefer foam core limbs over the boo core limbs. I like the carbon too. I plan to get some foam/carbon longbow limbs for one of my Cheyennes, but my Mini-14 ILF riser is very similar in feel to the Cheyenne riser and I already have the foam/carbon longbow limbs for it. I understand that the foam/carbon recurve limbs are nice too, but I don't have any of them either. You will be happy with a Morrison, but one may make you happier than the others. I would suggest getting the foam/carbon limbs. You pay more but get better performance and a very smooth, consistent feel. Bob builds an outstanding bow and is a terrific guy to boot.
