I am looking for advice regarding the best length for the i.supershape speed. I am 29 years old, 6.0 ft tall, 165 lbs (slim but in decent shape). I am a level 7-8 (probably closer to 8) skier, and am looking for a good frontside ski for the northeast hardpack for varied -mostly medium - turns. I definitely like slalom turns but don't want a pure slalom ski anymore. The past few years I've been skiing on Atomic SL 9 (160 cm) and Fischer RC4 Race SL (170 cm) for my hardpack skis. I want to have something with a slightly wider radius now, but not quite in the GS range. I demoed Blizzard 810TI in 181cm, the Nordica Fire arrow 84 pro in 176cm, and the Salomon 24h Max in 170cm. I liked the stability of the Blizzard and Nordica in longer turns, but generally favored how the Salomon turned in both medium and short turns. I also tried a friends Rossi Hero Elite ST-Ti in 170 cm, but that was too close to the atomic and fischer I had.
Based on the above, can you guys give me recommendation on the i.supershape speed (170 vs. 177cm)?
