5-9-11-13-15 dekany
A 15-odd-limit Dekany. This creates a scale of 1 1 13/12 11/10 11/9 13/10 13/9 3/2 143/90 5/3 11/6 2/1, with steps of 13/12 66/65 10/9 117/110 10/9 27/26 143/135 150/143 11/10 12/11. There are three perfect fifths spread quite widely around the scale, giving you multiple good rooting points, and only one small step that is melodically awkward, making this above average overall in compositional potential, with many interestingly xenharmonic chords.
