There are FIS norms for M, W, and Jr.'s. A U16 (for 14-15 yro's) FIS norm will be ~23M and run 180+, but much below that (17Xcm, <20M) the Jr skis also are softer and lighter so usually not a good choice for adults.
A "cheater race ski" is any non-FIS ski marketed to the masses, "cheater" because one can get an 18M radius ski to make a 27M+ turn, but getting a 27M+ ski to carve a 18M requires both technique and brute strength and is very tiring*. All the big brands- atomic redster G9, Volkl racetiger rmotion, Rossi, Fischer, Nordica, etc make a non-fis ski that fits this mold (~18M+/- and 175-185cm sizes).
And yeah, sharpen the edges 2*/1* or maybe run 3*side/1*base on any rec ski and that should greatly improve hard snow performance.
(*4 prs of M's and W's FIS 188+ 30M & 35M GS skis collecting dust in the ski room, while the 23M ones still get used).
