But I remember a few seasons back on other skis being frustrated the first season. Then it was the glide, though.
Skiing on what this year has been pretty much unrelieved hardpack-to-ice, almost entirely man-made snow, I have repeatedly seen the edges (not just under the binding) looking gray at the end of a day of skiing. But brushing them out (stiff horsehair, maybe a touch with fine steel) brings it back to glossy black, uniformly across the width of the ski. As in, no particular need to clean them up further or add another coat of wax, though sometimes I do, just on general principle. MN snow at 0 deg. and sandpaper have a lot in common...
Are you suggesting that seeing that gray is more than wax being squeezed out (dragged out?) of the base? That there's actually something there that needs dealing with?
And OP: yes, Fiberlene Pro sheets. Hard waxes are most of what I use (Dominator hx77 and Bullet), and they don't flake or chip, ever, except at the very tips and tails, where the base didn't get warm enough and/or the wax is a little too thick.
