Oh god all of those variables makes it difficult to pick out what is important and what should be skimmed over. Also these following questions aren't just for you so don't feel overwhelmed.
He made it sound like density is the end all be all in a sense of only having UHMWPE base material to work with. But in the other thread and as many state that a higher density means more maintenance even though the article kind of alludes to it being tougher and more resistant to dirt. So that's a conflicting idea that I might have just read incorrectly in his article.
Also if dirt is the biggest concern a harder material with the same hydromorphicity would produce a better glide over time with less maintenance, even though he implies that no maintenance is really needed anyway. And if no maintenance is needed why do people complain about keeping your bases "in good condition" when the only difference being the amount of dirt on them?
If nothing more is needed other than water to provide lubricant and a non-waxed base is the fastest what does this mean for "dry bases", by that I mean visibly black bases turning white- does it mean that the snow wasn't properly melting because of colder conditions? I assume that because they tested in warm conditions. is it because the snow can cause micro-cuts or whatever you wish to call it?
I understand the purpose of the hot scrape to remove dirt, but is that the best method if you don't want a waxed base but you wish to remove dirt? Maybe just some sort of manual grind is sufficient.
I really hope Kuzmin is still perusing that subject as there are a lot of unanswered questions and I am not even digging through the surface on mine.
