The worst conditions I have had them in was a tournamnet in Guntersville. I was on the trolling motor most of the day with just short runs on the big motor. The wind was blowing 20mph gusting even higher. They lasted just fine. This was with a 101 Fortrex and my PII. I have not had a chance to push the envelope with them on my Cougar and 112 Fortrex.Hole shot is better and virtually eliminated back splash on my PII. On my Cougar, it made less of a difference in back splash but hole shot did get better.
