Not enough, I enjoy waiting a few years after a flagship is released and getting it on the cheap to see how it performs. Nothing has changed enough in the last ten years to make me want new prices. Stable of a PSE Evolve and Mathews Drenalin. Drenalin still hammers at 60-80 as well as any bow I've shot. PSE is just a bit faster for hunting. Will be looking for a Mathews Traverse in the coming years cause surveying.
Typically a western setup and a whitetail setup. I'm debating finding a bow I love, and buying two for two identical setups.
I'm also debating buying a third bow, having a western, whitetail, and 3D specific setup because I like to tinker and try out new accessories and bows.
I’ve only needed one (Mathews DXT)since 2009 so it continues to be the only one i own until it stops killing deer for me. Worked like a charm again this year.
Perhaps a recurve would be #2 at some point though to buck the ever increasing technology trend.
