There wasn't any "compositional weakness" in your original "A" scale. Disjunct tetrachords divided for a resulting diatonic octave scale? That's a "classic" scale structure, in a real way, like, "a very large part of the world's music for the last several thousand years has used this same basic structure".
And it sounded really nice harmonically and melodically, not to mention it had stuff like some downright traditional alternate cadences, vii°-i, IV-i on the original tonic for example. IMO you shouldn't dump it yet, though I'd recommend dropping the third a couple of cents, to 63/52 (mirror image of the 13/7, 3/2 the mirror).
I think it be a shame to simply abandon a scale with a unique flavor for no real reason.

The more I played around with that idea the more I realized you were right and my "tempered" Ptolemy Homalon scale needed some tweaking.

> Kalle and others, what do you think of this scale and what do you see as its still-standing weaknesses so far as compositional flexibility?
