What I also believe: For non pros it is really also important that we feel "good" with the gear we bring, that we enjoy using it, that we feel we can do what we like to do.I also have the S007 with 4 lenses but I am trying to sell that gear as the IQ of the H6D100c is just so much better. I will take my H6D100c 50, 100 and 150mm and leave the 300mm at home

If-for example-you feel the H6d IQ is the one which satisfies you (and the S not), and if you feel its fine for you to schlepp it round, thats all that counts for you.
Of course my CL is lighter than my SL+16-35, but if I feel I have more fun with the SL than I bring the SL and accept the weight. The same for other cameras. As long as we are not doing really extreme hikes one can carry a lot if one wants to.
If I can carry my paraglider in a backpack with 15kg of gear up a mountain than I can certainly also carry my MF gear on a trip.
I think a good backpack and a wise selection/reduction of lenses helps to avoid the Sherpa-feeling.
