To each his/her own. There are dozens of single cam bows, binary, cam and a half, and whatever else out there by numerous manufacturers that are absolutely sweet! Smooth draw and excellant speed. Absolute killers. If folks want to dish out more money for more speed, good for them. Really, there's so many good bows out there, what is the point in regurgitating the same ol' stuff. I didn't own a switchback, but the guys that did told me the Drenalin was no real improvement, and not worth buying if you already owned a Switchback. I own a Drenalin, and to me, a Reezen is no real improvement over the Drenalin. The draw is harsher, so maybe its not even up to the Drenalin. How much more can they improve a bow? Only thing left, is speed. By designing faster bows, its something "better" and they'll eventually figure out how to better the draw cycles. Something has to keep them in business. The number of people who buy a new bow every year or two, pales in comparrison to those who shoot a bow for five years or so. Year to year, the improvements don't appear to be much. Look at it every five years. I say make em' as fast as you can! Only helps the industry, and the consumer. Nobody forces anybody to buy anything.
