I used to use the WASP 125 Cam Loks until the Rocky Advantage came out abut 5 years ago. Rocky Mountain has always been a strong name in the industry, and the Advantage are a stellar example. I was a bit worried at first by the small cutting diameter of only 1 1/8", but I have yet to have a problem with them. They fly straight and true, and what more can ya ask for?? lol
