I have a (couple) question/statements...
1)
Kai-V, with all due respect, I think Shinobu is right. I don't know much about Plastics, but some of the stuff in that article doesn't make logical sense

. Again, maximum respect, no offense whatsoever.
2)
shinobu, why don't you just help out with editing it? It would probably only take a few minutes, and all the tests you need have been done already, so it wouldn't take long to approve.
Now for the question part...
1) I couldn't find the discussion, so could you guys give me the outline for why exactly tips cannot have LAD? I mean, if a combination is using EWD, when the combo has fallen onto the wide edge of EWD, rather than the sharp tip part, hasn't it fallen over? Does it have to be spinning on the track, or can it just be the edge of the tip?
2) If tips really can't have any LAD, should we say that they give the combo more LAD? Just so that we don't refer to the tip itself having LAD? Because the term "precession" is a good idea, but it could take a while to catch on.
