You can adjust the zipwakes.......both in reaction times and everything else. I find they're not necessarily good with list when you're running and you need to correct for that yourself with the thumbwheel. I usually adjust the trim of the vessel manually with them, and let them deal with the roll automatically. They are very good at stabilization on something like you're 42' at cruise. You can break them if you have them all of the way down and back down on a fish.
