Mode 30 in particular is interesting because 30 is the product of the first three primes, so it is a fairly good choice if we want a tonic that is not a power of two. It contains modes 6 and 10 as subsets. We have the classic minor triad (from 10), the subminor triad (from 6), two major triads in 30:37:45 and 30:38:45, and the Barbados triad of 30:39:45. Chords not based on the tonic include the harmonic seventh chord (32:40:48:56). A good 13-limit subset with 16 notes in it is 30:32:33:35:36:39:40:42:44:45:48:49:50:54:55:56:60. | Mode 30 in particular is interesting because 30 is the product of the first three primes, so it is a fairly good choice if we want a tonic that is not a power of two.
