Bows are getting faster & faster is there a top speed.AND what is it.The cams wen't from round to triangle to oblong. what shape can give more speed then that. twik twik everthing on a bow is about twiked to the limit. I think sorry about the spelling.
As technology changes and improves you'll see faster and faster arrow speeds. Speed isn't everything though. I would gladly take a slower single cam that will deliver more consistant arrow speed and delivery over a double cam. The double may be faster but it also takes more tuning to keep timed properly.
I'm a hunter though, I want to be able to practice and hunt all season without having to worry about tuning. Tuning is for the time of year when nothing is in season.
