@joel, very interesting. Not sure if they are myths or superstitions??
Number 1. I ski with NO ONE who could pull me in the course straight and yet keep me in tolerance for speed. I would say in our ski community, perhaps a handful of folks could do it consistently, reproduce it time and time again and stay straight.
Number 2. I’ve actually done. 32 off, 34.2 mph and had boat driver not tell me what setting it was, when I would get to the end, I would offer a guess. Only one’s I got correctly, A1, C2 and C3. It was fun and I would highly recommend it.
Number 3. Done it as I am sure everyone has. Surprisingly enough for me, I really ski about the same with both. I do think a neat “experiment” would be to hand your ski to someone with acumen on setting up a fin, having them put settings on, go ski, come back and give the person your ski and have them “change” the settings or perhaps they leave it alone and see if you notice a difference.
The myth I always question is cold vs.warm water. Does cold water demand changing fin/bindings/ wing?? Does warm? I have asked several pros this question, and the majority answer is “I can’t tell you the last time I even checked my fin settings.” Do I believe them…Meh prolly not, but specific to temp changes they down play the significance of this phenomena.
I think there is so many “individual” variables to our sport that myth or not, superstition or not, everyone has their own philosophy or thought paradigm for their own skiing.
Other myths: hand placement on handle, doing opposite what is typical for LFF/RFF, does it matter?
Rear toe kicker vs. back boot. Length of ski? 65" vs. 68? LFF skiers are at advantage due to only 2 toe side turns, 2 and 4.
Literally one could give up their entire ski season doing experiments and myth busting. Since Illinois has such a short ski season, I would offer a suggestion on picking two myths, spend two ski days on each, report back on findings. Or you could assign a myth or two to your loyal web site congregation.
Oh just thought of another one: videoing each set. Does one actually learn and improve from watching and reviewing their set?
