I've never been exactly "with it" with respect to how various subgenres of music classify themselves, but here's a few ... "progressive" ... scales to try:
Octatonic: C C# D# E F# G A A# C
Basically, this just alternates whole and half steps. My example scale there starts with the half step because I like that "refrigerated" sound, but you can start with a whole step just as easily and get a leading tone up top. Another reason for the half step on bottom is that you can get both a major and minor triad starting on the bottom of each half step with this scale. This is important. I think jazzers might call one or the other (maybe both?) of the renditions of the octatonic scale a "diminished scale."
Whole Tone: C D E F# G# A# C
Goes up by whole tones...Pretty simple. If you like double and triple stops, try parallel major thirds, tritones, and minor sixths moving in whole steps with this one. Be careful with the major thirds (also m6), or you'll end up sounding like the end of a mario level. for Triple stops, try (C,E,A#) or the equivalent, once again moving by whole steps.
"Picardy" scale: C D E F G Ab Bb C
I made this scale (I think) and its name up. Sounds particularly good descending. Also try sticking that E on bottom and double stopping a m6. Note the refrigerated sound when descending toward the 5th. Use this.
