As noted above, the 17 microns (or whatever) would increase, as well as the cut into the base the deeper the edge cut below the minimum needed to change the bevel to a shallower angle. Though it may be bad form for a purist, it seems very doable, in a short period of time, to deal with the base difference by hand as it is very, very, very thin versus a base grind if an individual felt confident enough to do so and wanted to save a few bucks. (Especially in light of a lot of posted disappointing base grind results.)
Of course, I'm going to have to mess around with this, but I'm sold on the 1° base bevel (versus a .5°) and going from a 2° (or so) over the past 6 or 8 years, to a 3° was a noticeable positive difference, but not life changing. (This reinforces my belief, that as individuals learn how to increase their accuracy, it's not the end of the world if the side edge isn't dead on 3°.) With 30 plus years skiing with flat filing the bases and edges and 90° edges in the back of my mind, it's hard to visualize how these minute changes are really going to not easily be adapted to without micro analyzing it as you big dawgs have done. I still think (for me anyway) that if I tried this on high performance gear versus my stuff, the differences would be more easily felt, given that stiffness affects the transfer of feel.
(FWIW, I did receive a call the other day from a friend who used his Razor for the first time with Volkl bevel specs (1/2, I believe he said). Up until then, and as an old school, former shop tuner, he's been tuning his family's gear with a 90° edge and no base bevel. He was clearly amazed at how different his skis turned and carved. He loved the difference and was ecstatic.)
This is all very interesting and thanks all for clarifying the finer points.
So jamesgig, please let me know what you decide and do......and the results.
Again, for better understanding, what are the real tolerances of a base grinder and operator, which is probably variable?
And for a counter point I find humorous, shows ingenuity in a pinch and telling:
|...........a hotel room key..... - when placed between a file and ski base it produces a 1 degree base bevel angle (I'm not kidding, one of the <edit> team techs actually uses room keys when on the road).
