I have a 171 star boss that holds against the wind beautifully. I stopped throwing high speed stuff recently and went back to 9-11 speed discs with the exception of my boss for big hyzer shots and for windy days. I've thrown a Vulcan in a headwind screwing around, really trying to launch it, it just turned in to a roller that came back just about even with the tee pad about 200 feet to the right. It was pretty comical how fast it was rolling right back to me. We estimated that it went out about 250 feet before hitting the ground and rolling back.
