Clearwater, you can order them any way you want them. Dual cam, single cam, single cam with a perimiter weight. Different riser and limb lengths, and target colors. They offer limbs at 90+ lbs, but the waranty changes for the higher poundage limbs. I think they offer 80 lbs limbs standard on most of their bows. I have a dealer near me that builds them and they are pretty nice. You just don't hear much about them because they don't really advertise.
