an aversion to cables is not going to be helped by replacing pedals with modules, is it really? - you're just shifting from one set of cables to another and probably more of them as in rack effects want modulating...

but saying that:

what pedals do you wish to replace and how much racks space do you have to house them?

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

sound sources < sound modifiers < modulation sources < utilities
