A friend talked with Hoyt Tech last week. He has a 2002 Ultratec with command cams. Hoyt informed the change could be done but since we're going from a 2 cam system to the cam and a 1/2 we would loose 10 to 15 lb of draw weight. That means a new set of limbs would be in order and possibly string and cable. He didn't talk about a 1 cam to the cam and a 1/2.
