First off the price was $669. Probably will end up the same price as a Hoyt Vtec.
I think the 308 IBO was with a loaded string.
The initial pull of the cam( it isn't that bad) is the toughest part of the force curve. After that you are going to smile(it feels like a wheel, smooth, no bumps) until you hit the rock solid back wall. I think the drawstop works the same as the I, F cams. I really liked the way this bow felt during the draw cycle and the shot. Check with your local shops. They should be arriving this week. I think most people will like this cam and Bowtechs new lineup for 05.
