I average more than 100 days a year, recently. Lack of skiing is mostly not one of my problems.
A "cheater" is a ski that is not built to FIS race specs, that makes either SL dynamics turns (short turns), or GS dynamics turns (longer), easier; and thus has a longer turn radius for SL versions, or a shorter turn radius for GS versions, often. It is also likely to have a bit softer flex, for the same purpose; with a shorter turn radius, in the case of the GS versions, so the skier needs less space moving down the hill. Some folks use these skis just recreationally, because they like the roller coaster, precise feel of race skis made more easy and practical for non-competitive skiing. Others use these skis for beer league or club racing; but this is probably a secondary use, mostly. Such skis are very popular and mainstream in Europe - available as rentals there routinely. They are relatively scarce in this country. Brands often don't bother to market them here.
I prefer the GS dynamics, and the corresponding cheater skis: great in 175, 178, 180, 182, 183 and 185 lengths, mostly with shorter radii than race skis would have at corresponding lengths. (I like and own the FIS skis too.)
