      I'm not familiar with JT9 so I have no comments there, but as for power consumtion I will offer what I know.


      first off I do a fare amount of SOTA and therefore have experience backpacking all the gear to the top of a peak and weight is a big factor at times depending on the dificulty of the peak that needs climbing. Also as said in another post, biggest bang for the buck power wise. We SOTA guys mostly go QRP for obviouse reasons. LiPo batteries are the way to go, they can be a little dangerous to charge at times but they will give you the power you want at a light weight. I use an FT-817 but I have friends who use KX3's and they have used these batteries too. you need to get the battery and a smart charger. I can charge up 2 of these batteries and spend ALL day calling cq on SSB and still have a little battery left over when I start back down the hill. just a thought, and if you are interested I can get my batteries when I get home and send more information on them, IE: model # of battery and charger.
      now I say these are the way to go, but just an FYI, they are external battery pack that will work on the radios with a small pigtail you may have to make. As for the the internal battery I use on my 817 also, that battery pack is a 2700 Ma NiMH, and it also will give me several hours of CQ calling on SSB (I'm not confident with my CW yet)


      I do have a question as to what antenna you are looking to use for the trip?

      I'll second that, and it's not just the
      radio capabilities that cause issues with JT9 on 6m. I often
      see strong reflections with a fast Doppler shift just below
      JT9 signals on 6m and that component seems to degrade
      decoding severely. I assume these are aircraft
      reflections.
