Misread what I said.
"in the first one you didn’t mention hypo modes once instead something about playing the 6th of the major scale."
Your quote. If, for example you want to find phrygian for A, the scale is F (the b6). The mode or hypo rule, if you like, then follows. Very simple. Not much to memorize or to learn by rote.

As for tritones, I don't agree with you. Your view, to me, is far too complicated. I, don't think correct. Your resolutions are in the wrong context and direction. I simply don't understand what you know. I also don't want a mass debate. In roughly, 35 years of playing, performing and studying, I've never heard nor read, this view before. Have at it, it makes absolutely no logical or rational sense, to me.
