Guess for some background first, ISIA full time instructor working in Switzerland as a trainer for a ski school, and a senior instructor.Race and Freestyle coach and ex FIS racer. Trained bootfitter, sponsored athlete & brand ambassador for one of the major ski companies, and will be spending the next week training retail staff in the UK about next years equipment!
New technology has lead to hundreds of different Torsional stiffness materials such as flax, hemp, plastics and titanium, super fibers, polymod Carbon and Koroyd have changed ski design and performance dramatically.
Saying shorter skis are slower is wildly inaccurate Slalom skis 165 are stable up to speeds of 90- 100 kph. A punter rental ski with composite core with 165 length will struggle at 60 kph. Different construction but the same length. Lower end Rental skis tend not to be sidewall construction and composite Foam cores. They will be very different to a wood core sidewall ski of the same length.
Length of ski for beginner varies, depending on build, weight and boot length. Yes rental shops will shovel Kuhscheiße as they just want you to take what they say and get you out. About eye level is a good rule of thumb these days. If the skis are to short yes they are easier to turn, but they are much more unstable and vibrate more, making them more difficult to control, increasing fatigue and impeding technique
Longer skis can cause more damage in a fall by creating greater twisting forces on the joints. So shops will play it safer as the falls on shorter skis reduce that risk by a marginal %
The standard Austrian treatment in a rental shop is get them in and out as quickly and as safe as possible, with the skis that give them the biggest profit margin!
