I've noticed that I am using mostly the elements, delay and erbeverb for sound design, and feeding in a lot of sound sources from my computer. Because of this workflow I really have come to think for me the way to go is to add some more effects modules and maybe even sell the two 4ms modules (much as I like them, just not using them much), hence the original post.
@Lugia: thanks for your suggestion but I really feel comfortable with using effects in modular like that, and for my workflow atm it makes a lot of sense to continue in this direction.
