Some things to consider from my experience: 3xMIA for utility (if you can find one); Melotus Versio as an alternative to Arbhar (can be flashed with many different firmwares for other effects; smaller and cheaper); Batumi for playable LFOs; C4RBN for a small multimode filter with some character; Ikarie for a slightly larger filter with more character (and stereo possibilities); Ferry for outboard effects (there are some great pedals out there); HPO so you can easily listen standalone.
