I just cracked the lower limb on my '04 LX today, and I was wondering if anyone knew if Mathews replacement limbs are made by a different supplier/manufacturer than original? It was a little unnerving, especially since I've never dry fired the bow, Iuse limbsaversand I always shoot 450+ grain arrows. These were the original 60-70lblimbs btw, maybe 1000 arrows shot since last fall when I bought it.
