Thanks for all of the excellent comments.
My first thought about skier height vs ski length was, "Almost all male SL racers ski on 165 cm skis and most of them are fairly big strong guys. The don't seem to have a problem with having too much leverage for short SL skis" I've skied 165cm race SL skis and they definitely didn't feel too long to me but SL skis are stiff so maybe they are an exceptional example. Now I realize that skier height influences leverage on skis. At any rate, Now I believe the longest skis are designed for the tallest and heaviest and fastest skiers and the smallest ones are for the shortest, lightest, slowest skiers that would want that type of ski.
Here is how I will put this info to use. When trying to pick a ski length, without demoing, I want to know what length the ski designer would recommend for me based on my weight, height, ability, and goal for that ski like turn radius and float. So if the average male skier weighs 182.5 lbs (the average of american and european men) and is of average height. that gives me a good starting point. Here is how I will calculate how I compare to average when shopping for Head Monster 88 skis.
criteria affect on ski length
170 lbs (lighter than avg) shorter length than average
5' 10" (Average) average length
average ability for customer of advanced/expert carving skis = average length
average speed for customer of advanced/expert carving skis = average length
for these skis prefer tighter turns to firm snow performance = shorter than average length
Head Monsters are pretty stiff = shorter than average length
Therefore, my new Head Monster 88 skis that will arrive Friday should work well for me. They are 170 cm which is just shorter than center of the range of lengths available: 163, 170, (no center length ski), 177, 184.
Thanks again for the help. Please let me know if it seems like my calculations are off.
Edit: I just realized that all I really needed to know is the average weight of men.
