skis are definately getting better. Example...Lines skis for next year have a 65% thicker edge so that your not going to get cracked edges from rails AS EASILY as before. Their bases are reinforced harder sintered ptex for an almost solid base (ive seen and ski'd them over cheese grater and rocks, and there varely are any marks other then dirt from the white bases).
Like everyone else said, we use our skis to the maximum potential. Of course my 5 year old slamom skis look brand new, thats cause i took them down groomed runs and never jumped them. The flex pattern of any ski isnt intended for landing on the tips/tails (no matter what the Pep Fujas flex pattern is). These landings stress the core over time, and the ski will lose its responsiveness
if u buy a ferrari and drive it 50 miles per hour all the time, the engine will drive like its brand new for 200,000 miles. If u hammer on it, its gonna last alot less.
But yeah, I know Line is making their shit super durable next year, so skis are getting better
