I've run C31XRs at two different QTHs, with triple feedlines on any two
bands at the same time, at 1.5 KW, with zero problems for 48 straight hours.

In both cases the feedlines came to stubs, then Dunestar 600 BPFs (100W
rating).  Neither the stubs nor the BPFs (whether then can handle the power
or not) were sufficient, but together things were fine and band-to-band
interference was nil.   FT1000MPs in all cases.
