@Psyjafo Hi, welcome on Psynews and thanks for your support
First of all, about the rolling bassline it has been popularized by Full-On but most recent Psytrance productions has a rolling bassline too so it's not peculiar to Full-On. For the classification of the artists you listed I'd say :
- Ajja is usually just Psytrance on his LPs at the exception of "Spira Mirabilis" which is somewhere between Psychedelic Downtempo and Deep Trance.
- Tristan as you said it, it's UK Psytrance and I think I will end to add it in the PDF. For this one I'd suggest you to ask to @Ormion, he's a better connoisseur than me on this sub-style.
- Whiptongue, from what I can hear by now on his EP ("Oscillate") I'd say UK Psytrance too.
- Jumpstreet I'd say Hi-Tech, but a slower kind of Hi-Tech compared to what we can hear most of the time in Hi-Tech.
- Fungus Funk from his last EP, "Fractal Funk", seems to has kept a part of his "proto-Hi-Techish" Darkpsy sound on leads and FX but, not surprisignly (this EP was released on Sangoma and Timecode records after all ), has a Twilight bassline on the 2 first tracks.
- Burn in Noise, from his last album ("We Stand"), it depends on the tracks, but there's blends between these sub-styles : sometimes it's UK Psyrance, sometimes a kind of slower Hi-Tech, sometimes Full-On, and some other Progressive Psytrance and even Psychedelic Downtempo/Deep Trance.
- Avalon, from his last album ("Rise"), it's UK Psytrance most of the time but sometimes there's blends with Full-On.
- Regan just made compilations so it woud be too long to classify each tracks from different artists.
- Mad Tribe on "Superstar" : a kind of "Full-Onish" UK Psytrance.
- Outsiders on "Be As You Are" : most of the time Full-On. UK Psytrance, Progressive Psytrance or Psychedelic Downtempo on some tracks with featurings.
- Sonic Species on "Tokyo Sunrise (Transient Disorder Remix)" : "Full-Onish" UK Psytrance too.
- Dickster (when he's alone) on "Inebriatti" : UK Psytrance.
- Braincell used to be Full-On back in the days (Transformation Of Reality ), now he's UK Psytrance with some hints of Full-On on his last album, "Gaia".
- Earthspace on "Machines Reflecting Love EP" : UK Psytrance.
- Earthling on "Radio Gaia" : sometimes Full-On, sometimes UK Psytrance.
- Electric Universe on "Lakshmi" like on his last LP "Journeys Into Outer Space" : Full-On.
- Astrix on "He.Art" : "Full-Onish" Progressive Psytrance.
I might be wrong but I think there's nothing Forest in the artists you listed
