While my ski heart is in the Austrian Alps (grew up right next to them and got to ski there a bit) I'm stuck here in the Midwest (USA). Luckily I have a small hill to ski near by but not much in regards to ski shops. So having to maintain skis for 4 people I started waxing them myself last season. This season I'm planning to tune them in order to maintain the edges. Only one set of skis are new (although cheap). The other ones are used and well loved. My skis are probably the worst and that's where my question is.
The tail end of my skis are concave, where the edges are much higher than the middle. This spreads about one and a half foot from the tail forward, worst being near the tail end. Seeing that the new skis are perfectly flat there and I have a hell of a time scraping the wax off there I was wondering if I could/should flatten them out there. I ponder about taking a file to it or to fill the area with P-Tex. Any suggestions or opinions?
BTW, I do have the tools for the base and edge bevels.
