Hi friendly modular experts!

Here's another post seeking feedback and constructive criticism on a potential rack. I already have a lot of these modules (current rack is here: https://cdn.modulargrid.net/img/racks/modulargrid_2104407.jpg, not sure how to post a proper link), but nothing is sacrosanct. Goal is to be a jack of all trades, but my main focus is on melodic generative music with a lot of playable sound mangling possibility. The image represents a Minibrute 2s connected to a Rackbrute 6u, with a Mantis case to the right.

General approach
Rackbrute - bottom row: usb interface, modulators, randomness and noise, s+h. top row: clocks, triggers, quantizers, general utilities
Mantis - bottom row: envelopes, mixers, effects, eq and output. top row: oscillators and sound sources, filters and effects.

I've tried to cover all my bases and be heavy handed with utilities, but it turns out I have 20 hp left if I stick with my current plan.

So my questions are:
1) what am I missing?
2) what do I have too much of/what's redundant?
3) how would you spend that remaining 20 hp?

Thanks everyone!
