Morrison actionboo vs older limbs

[strick9]

I currently have 57lb at 28" D limbs on my morrison td A riser these are Bobs old limbs not actionboo.
   Has anyone had same poundage in the two types, and was there a major performance difference between the old and new. I have located a pair of 59 at 28 C limbs in actionboo and a D set 65lb at 28 old style...would the effeciency of the actionboo cancel out the added poundage of the older style 65lb limbs.  Regards
