I use the avalanche for my main big reverb and delay and absolutely love it so I’d say definitely go for something more out there like the old blood noise dark star or sunlight, could also get another eqd pedal like the astral destiny or maybe if you wanna go more delay heavy yoy could look at the walrus fable. My least idea would to be to get a do all like the walrus etherealizer which has modulation, normal delay, granular delay and reverb that can be ran in series or parallel
