MNM - What 4 params to ctrl on Eventide Space / Timefactor?

I just ordered an eventide space to effect a dsi tetra and plan on buying a timefactor to effect my sp606 (drums/sndfx). I’ll be controlling each via my MnM and I’m curious what 4 parameters I should bind to the 4 CCs available on the MNM? I’ve read a bit of the space manual and it looks as if I can assign mix, decay, size, delay, low, and high. I can also assign CCs to Xnob, Ynob, Fxmix, and contour, which seems to be different depending on the preset/algorithm selected.

As for the timefactor, you have Mix, delay mix, delay time a, delay time b, feedback a, feedback b, Xnob, depth, Speed, and filter. I’m thinking of assigning the 4 CCs to delay time a, delay time b, Feedback a, and feedback b. I’m wondering if that’d be good use of my CCs or if I should choose differently.

Anyhoo, which 4 parameters on each the space and timefactor would you recommend I assign to be controlled via the 4 CCs on the MNM?
