So if I had to choose between 12, 17, and 19 tone equal tempered tuning, 17 has really strong leading tones, more so than 12TET, but at the cost of sounding like an old and out of tune piano.
somehow I thought you were talking about Sandy, Silvy-birb, Gally-birb, Baroo-baroo (Yona), Smoldy-woldy, and Celly-bug.
