I have never adjusted the fin on my ski in my entire life. I ski in Minnesota where the water temperature during our ski season changes from 33 degrees to over 80 degrees. I often have times during the season where I struggle and feel like a fin adjustment might help, but in the end I think it is just a mid-season slump and I am doing something wrong that I usually work out over time. I finally switched over to a 66 inch 2010 radar strada last year. It I set to stock settings (as far as I know). Can anyone comment on how they decide when it is time to make a fin adjustment? I have read some articles about the benefits of adjusting to compensate for cold water, but I’ve never done it. Any tips would be greatly appreciated.
