Either, I like the 2' chop better, alot less chine walking. My boat tops out at pretty much the same speed in most water conditons, just depends on whose riding and If they can take the ride in rougher water. Had some 3-4' chop today. Ran it at 63-65 gps alongside some poker run guys. I just adjust the tabs and bring the bow down a little to soften some of the blows.
70.8 gps in flat water, plenty of throtte to go, but chine walk started to get me. Haven't run it in a good chop wide open, yet, spend more time in the rough stuff at 60. Ran a Hydrostream at 80 top end on flat water, really don't care about runnin' a Sunsation in flat water at 75mph!
