BigE, you know, it could also mean that a ski demands more of one than one can easily deliver. For example, watching Bud rip up Big Sky on his little Solomon SLs blew my mind. He would rip these awesome, tight carved turns at mach schnell while I would watch him and think, "If I tried to do that, my legs would be falling off about the third or fourth turn!"
So, there's that kind of "work," too. That work that I experience on a real SL race ski. I have a lot of fun for the first few turns, but about the time I turn the ski in, I realize that if I tried to ski it all day, it would be like working out with the Broncos.
