Simon, Finsup - I agree totally. I have MWTs as surrounds. They are up on a pair of cinder blocks to get them above ear level. Although the right surround is pretty close to my seat, I do not get any speaker localization issues with this set up (see my system link for the whole rig).
I find it interesting that you have back surrounds from Ohm, too. Currently I have a pair of Paradigm Atoms on tall stands as back surrounds. Since I upgraded to Ohms for 5 of the channels, I have been pondering whether to stick with 7.1 or go to 5.1. But a pair of Walsh Walls mounted on the back wall is tempting. No funding available right now, though. That Mac preamp pretty much broke the bank. Oh well.
