One thing I retained from the Fin Whispering book was the theory that a setting that works in cold water should work well in warm water, but not necessarily the opposite is true. The idea is that there is a smaller margin of error in a cold water setup for a ski and your skiing style, due to the cold water being more reactive/dense against your movements. My latest ski/setup surprised me last year by remaining skiable well into wetsuit season. This year, I tried a few tweaks in setup during the summer to break out of a slump, but kept returning to the same basic setup. This fall, the ski is still performing well even though the water temp has dropped over 20°. May be the ski, but I think I may have just stumbled upon the right setup for me on this ride. I'm as amazed as anyone. :)
