RE: Bowtech -or- Matthews?
If you want something with decent speed and more forgiving shooting characteristics then one of those three criteria I mentioned earlier (brace height, draw cycle, riser geometry) should be somewhat more forgiving. For example, take a look at the Bowtech Patriot Single Cam. You are still talking IBO speeds in excess of 320 fps with a 7 inch or better brace height. The riser is still relatively heavily reflexed and the cam is not as smooth to draw as their Freedom cam but the slightly larger brace height should add some to the forgiveness level of the bow.
Same thing goes for the Mathews Outback (while not looking at the axle to axle length). The Outback has a slightly larger brace height to add some forgiveness though it also has a moderately reflexed riser and a relatively stiff drawing cam.
My suggestion would be to look at bows with brace heights over 7 inches and IBO speeds over 310 fps. Axle to axle length should be at least 34 inches in order for to get some forgiveness from that aspect of the bow's design....though the actual riser/limb configuration also play some part in it.
Hope this helps.
