I do like that way of differentiating chargers. Out of curiosity, what would you put into the purpose built charger category? To me the "obvious" recent includes are the M-Pro 105 and Sender Squad. I'm not sure about stuff like a Mantra 102, Katana 108 or Cochise.Probably posted this up thread a few years ago. But bears repeating. I think there alot more stout am skis that can be charged on, than there are purpose built as chargers - well suited for charging in "all" conditions. Sometimes a good am ski is all you really need.
Another point is that to me charging is really an open terrain thing. If the lines get smaller the skis I want for charging changes - a lot. Want a much slarvier ski for the chutes than in the bowls.
It's also true the real big guns kind of suck in tight terrain. It sounds kind of dumb and/or insultingly obvious to say it out loud but I do think there's at least as much variance in optimal skis for terrain as there is in optimal skis for snow pack, despite the snowpack stuff getting most of the attention. I would choose different skis for Highlands and Crested Butte, I suspect the same is true for almost everyone.
