Phil has much more experience than I with the entire line. I got 275 fps. with my Wheely. That was with a 378 gr. arrow, 62# and 29" draw. The Wheely is very easy on the shoulder, as it gives you the full peak weight early, and then drops off to a lesser weight for most of the rest of the draw. Very easy and smooth to draw for me.
I am surprised to hear that the Dually had more valley than the Patriot though. A friend who drew one seemed to think it had no valley at all. Perhaps it was a synch issue.
After drawing and shooting some Freedom cam bows, I would say that they draw even smoother than the Wheely, and shoot with less noise and vibration, even though the Wheely is not loud by any means.
