Thank you for your constuctive and well thought out remarks. They make the statement that you are really the person who should be criticized, not those who are making justifited opinions.
Personally, I like switchups because they are fun to do, and add a bit of difficulty to rails for me. I have messed around with sliding back and forward under my bindings, as well as doing mini daffies while on a rail. These are fun as well.
Rail style, like any style, is determined on a person to person basis. What I think is cool may not be the same as you, and therefore it is difficult to judge "skiing" as a whole when the personal interpretation of what skiing is factors so heavily into how a skier views the sport.
 I challenge anyone who does not like a particular part of their skiing or wants to do something new to change that aspect of their own skiing, and let that creativity come from a personal level rather than doing the latest trendy grab ( truckdrivers, for example) or learning the latest style (geurilla steeze, a couple of years ago). To me, innovating for my self is far more pleasureble and rewarding than learning the lastest trendy thing in a video.
