Thanks and I may swap out the SBG and Zeroscope to free up more space as I don't really use those two modules as much as I thought that I would. Waiting for others like Jim and Lugia to chime in what would be great additions as well. Thinking Disting EX+ PNW + sequential switch + Matrix mixer and maybe 1-2 more oscillators as the BIA and Cursus are more all in one modules and having a solid analog VCO and FM module would be great fun. Perhaps Plaits and Rings? IME Hertz Donut Mk3 looks great as well but it is digital.
