3-5-7-11-15 dekany
A 15-odd-limit dekany. This creates a scale of 1 11/10 7/6 5/4 77/60 11/8 7/5 3/2 7/4 11/6 2/1, with steps of 11/10 35/33 15/14 77/75 15/14 56/55 15/14 7/6 22/21 12/11. With three perfect fifths, including a full harmonic seventh chord above the root, this has both familiar and xenharmonic sounds to play with, and although some of the steps are slightly below optimal for melody, there's more than enough good ones to make this scale compositionally effective, putting it above average overall as dekanies go.
