Joeman, I ran proos from 03 thru 09. They always pulled a 12lb weight whenever ask to pull. They seemed to be built well, They with-stood all the abuse my challenged crew could throw at them. The only reason I'm not running them anymore is I won a pair of Cannon's.Paulywood is correct Thunderduck- Capt Willis does run them on his boat and sells them out of his store Fish On Tackle #616-935-6985. I'm sure he would answer any questions. Too Fish
