Hi Joel, In relation to skiing in cold water, we have a lot of experience here in Ireland. I would say that the way the ski reacts in different temperatures is marginal. I would say that the overall cold water skiing experience changes many things about the session. Cold skiers tend to stiffen-up, so much of the feel is lost. Cold hands, cold feet, cold knees, its not pleasant. This probably give the impression that the ski is performing differently. Loving the videos. Keep it going. Regards. Chris.
