RE: Switchback speeds
I really don't think you will have to worry about the accuracy of the bow. I am sure it is a fine shooter as mosst of the mathews have been the past few years. There for a while 5 years ago or so he had a few bows with a pretty low brace height so he could gett he speeds the consumers were demanding. Looking at the specs it should be a fine shooter[8D]
Sorry I can't help out with the speeds I do not own one.
