In past years, I was uncertain about what I could do on skis. What was me?, what was equipment? I was "learning". One of my ski mates would always ask "what wax are you going to use" as we made our evening phone arrangements. That got me in the habit of doing something.
This year I skied every week. I carried three pairs of skis and I got tired of worrying about them, but had come to know what well prepped skis feel like. They turn!
Now, I a spend about 15 minutes to tune my skis. They feel good, and the world is a wonderful place to be in. I love the time spent at the ski bench.
My daily drivers need to go see a stone, and the shops have drained their coolant for summer. The bases are high in the center and low near the edges. I am NOT going to hand sand them flat. I am not even going to file the edges or wax the bases. I am going to clean the bindings and keep the skis indoors and rust free. Next fall, I will start with "new surfaces, and wax to my hearts content.
regarding shortening the ski life by excessive edge sharpening. ?
It's a good excuse to get new ones!
'think of the bragging rights, if you actually filed away all the edge before abuse of the bottoms turned them into "rock skis".
For those who send their skies through the "Montana" every other week, That's a lot to pay for a poor wax job. Grinding can remove a lot of material.
I speak of hand filing and stoning. Hot waxing with the old iron picked up at the thrift store. Base flattening is a once a year thing at most.
Racers would find skies with little edge width "faster" I am sure!
