Those birds done flown for lack of snow!
Snow seems very unreliable down there!

Just tune the sides and carefully use a flat file on the bases so as to avoid
the scales..
Bases basically flat..like old school..prob won't notice the lack of precision on the bases..

Knee does not appear to be dropping/dropped..

On my Alpinas, no problem..even if you scape off the
scales a bit, big deal! You won't notice climbing but they might
go smoother! I sharpen mine 1 or 2x per/season -- with one of
those cheap little red units..25 bux..

Point being anecdotal is to evidence as heavy is to powder..
