Guess you can chalk me up as a "me too"… I've got the MF in the loop after both the PF and TF. I did put it before Space, though. While it's not the same as, say a Phase 90 in the front, it comes very close. Juft FYI, my chain goes like this… Send >> PF >> TF >> MF >> Space >> Return.

IMHO, although it really does depend on the sound I'm going for, I almost always put modulation after delays. Otherwise, the delay tends to "smear" the modulation when the echoes start piling up (which is not always a bad thing). With the modulation after the delay, each repeat is modulated at the same time and in the same way, which tends to keep things a little cleaner or better defined.
