Larry Blackwellwrote a review of Rossignol SYSTEM S7 Pro Mancini Ski on January 16, 2011
Bought Line 100s (179s) in 2008, S7 (175) in 09 and JJs (174) in 2010. Seventy years old, 185 lbs. At 70 yrs old, speed is not priority, agility is. The Lines and the S7 are faster than the JJs. Both are noticeably heavier than the JJs. The JJs are fitted with Salomon 12 N Ti bindings, very light, and the Lines and the S7s are fitted with Markers. For me the JJs significantly improve ability in powder, bumps, everything.
What a ski. 5 stars for JJs.
