I run into this problem every time I try to do a light poundage bow, 30-40 pounds. The limbs are so limber that you can shake the bow and the limbs flop, yet it's probably close to 50#. I think I know what the problem is but would like your input please. I have a stack of .227, 1 piece of .043 clear ULS, 1 pc .050 clear ULS, 2 .030 veneers and a .002 taper, .074. Thanks Tony
