I had a Pro 40 Wheely for several months last year. My problem last year was that I experimented with too many bows, and wasn't shooting any of them too well after a while. The Wheely has a nice draw curve (to me at least). It comes up to peak pretty quickly, then drops off a bit for most of the draw before dropping into the valley. Even with my two damaged shoulders, I could draw the Wheely at #68 with no problems during or after shooting. I can tell you that my best 50 yard groups of last summer were shot with the Wheely. I did have some issues with the valley and vertical double grouping. That was most likely due to poor form on my part, again from shooting and experimenting with too many bows. It seemed like the cams at 80% letoff were pretty sensitive to being synched exactly right. Most guys I know seemed to prefer the Pro 40 Freedom cam model to the Wheely, but either one is a pretty nice bow.
