[TowerTalk] SO2R or Multiop Contesting without interference

Is anyone out there operating high power SO2R or Multi-Op without interstation interference (besides being on or very near a harmonic)? 

I read reviews of various antennas, new filters, etc of having non-existant issues. However, in my limited experience it seems that tribanders will have these issues even with the latest high power triplexors and band pass filters. Even problems will arise at multi-tower stations with monoband yagi stacks and/or different direction facing yagi's.
Has anyone got the ability to say that they are trouble free on their various band combinations?
For instance, at home I have lots of interference when receiving on 15m and while transmitting on 20m. Same goes when receiving on 20m and transmitting on 40m. For me, it can be both direction and/or antenna limited depending on what band combination and which tribander that I take out of the stack. 

I'm curious about the true confessions that other operators have about what they are dealing with when transmitting on multiple bands at once? Have some of the stations got this under control? If so is it mainly the big property owning stations with many towers or have guys on 1-2 tower setups quelled this also?
