looking better - at least to me!
yeah if you already have modules keep them - people seem to really like rene
I often use the marbles 'grids' mode it's great for getting a drum pattern quickly - 1 thing I do though is to take the middle output and send it to a mutable instruments branches - which I patch to get (skip/open/close) - this may add a lot to grids too, I'm not sure - so maybe that and kinks would be good next modules
it's not a bad thing to have to wait for modules due to financial constraints - you'll learn a lot about how your modular works
tbh if it's a toss up between pams and maths - I'd get maths first
I'd also consider veils instead of the 3xVCA - 4 hp bigger and a little bit more expensive (but only a little) but you get an extra vca, which is never a bad thing

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