I know you didn't address your question to me - but I'm running Mani-2's with a Rel Storm III and it's a pretty unbeatable combination. Even though the Mani's can play quite nicely with no sub, they integrate perfectly and go to a whole 'nother level with it. I cross over at 31Hz.
I have no experience with Mod 1's, but previously had Sttaf's paired with the Rel. Integration was perfect and it was a very nice setup. Before I got the Mani's I considered the Mod 1, and in discussion with Totem was told the 1's have much tighter bass than the Staff (though not as deep - 38hz vs 50hz rolloff pt), and better mid-hi, so paired with the sub . . you can do the math. I'm not sure if this gets you to the level of the Manis with a sub or without though.
