If you are happy with the cams that are on the bow. Why change? If you are wanting more speed, I would look real hard at the charts and see if the speed increase justifies the cost of the new cams. Also the new cams may change the bow weight enough that you will need new limbs also.
The Nitrous at 315 over the Tru-Arc at 305 sure would be nice, If you can change cams without having to change limbs also, to mantain the same draw weight. It can get expensive. You could probably buy another used Cougar III the way you want it for the same money it will cost you to change every thing over. You can always use another bow.
