Good news! We had 14" of new snow today in Tahoe so I had my first chance to test the new shims for snow packing. This was "normal" powder for Tahoe, which would be considered heavy/wet for Utah and Colorado. If I remember correctly, I had snow packing problems with the Linkens last year under this same type of conditions. With the new shims, snow packing was not just reduced, but there was no problem with it whatsoever. I skied all day on the Linkens, zero snow packing.
I took a few runs on a pair of superloops, and my foot was wiggling all over the place -- I was so psyched about the Linkens' performance. We have two more storms expected in the next week or so, so I'll do some more testing soon, but thought I'd pass on the good news from the first test since I'm sure you are eagerly awaiting such feedback from the field.
I have to admit, I was skeptical that this would completely solve the problem, but it seems that the plate was dumping snow right on the old shim's horizontal platform and with each turn, a good portion made its way under foot. It was apparent today that any snow dumped on the new shim easily fell out of the binding.
These old/new shim test comparisons I have made so far are on the lower black shim only, though witht he extra yellow shim it looks like the clearance for snow to escape is exactly the same.
I'll post a more complete review of the Linkens with the new shims after a few more days of deep snow testing.
