Re: Brow tines
I think the term "three up" is misleading. I don't consider the main beam as being "up".
I prefer to consider it "TWO up", as it is simpler for me to count from the tip of the main beam inward, where I just look for (at least) two tines to be "up" off the main beam (disregarding the brow tines).
So it would be the two up + the main beam = 3. This is the minimum legal in the Western parts.
