I'd add an AISynthesis matrix mixer and kinks - multing your modulation to these will add more much variety than either zadar or batumi
looks like you'd have 2hp left for a 2hp trim module or a dreadbox div
I agree about maths - it is way more than the sum of it's parts - check out the illustrated manual online for (self) patch ideas
another option would be to buy another case now instead of a module - that way you don't have the I only have xhp left itch - hehehe

Utility modules are the dull polish that makes the shiny modules actually shine!!!
