5-7-9-11-13-15 pentadekany

The most complex 15-odd-limit pentadekany. This creates a scale of 1 143/140 15/14 11/10 33/28 9/7 13/10 39/28 99/70 3/2 11/7 117/70 9/5 13/7 27/14 2/1, with steps of 143/140 150/143 77/75 15/14 12/11 91/90 15/14 66/65 35/33 22/21 117/110 14/13 65/63 27/26 28/27. With four perfect fifths distributed all around the scale, plus an unusually high number of imperfect but still recognisable ones, this is quite usable despite having a couple of melodically awkward comma steps on one side and no simple 5-limit chords, forcing you to get to grips with neutral and gentle ones instead.
