Most likely the E41-B's just to get a good match across all 5. Not sure if I should hone in on a T-1 for a center or that 6100 though. I think the 6100 would be easier to accommodate since it's not as fat, it's longer/skinner. Got quotes on each of them and they each cost pretty close to what I paid for the T-2's with the subs and sub amps...
Apparently I got a pretty good deal on the ones I have.
