swap typhoon in instead of pams (and move this to last in order) - in the 4 starter modules
next module after those should be a quad cascading vca - I prefer veils (more gain), but the intellijel is also a good choice - as both of these amplify (most vcas are actually attenuators) - and you can use one of the channels to amplify the sub37 - not that you should need to - clouds has loads of input gain - typhoon should be the same - so try it first (you need a 1/4"->1/8" cable)
I'd probably choose between o&c and pams - and use the money saved to get some simple utility modules - logic, mixers, sequential switches etc

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