i dont think there is anyway for u to lower the draw weight without purchasing new limbs. but, if u shorten the draw length an inch it just might lower the pundage. it really depends on the bow. my rage is always at the poundage u set it at when changing draw lengths but my old fred bear would change the poundage when you shortened the draw length.

there also may be cams with more let off for your bow. i would call your proshop and ask them. this would still have the same draw weight but would make it easier to hold back.
