I don't mind the weight, I carry the Sigma 70 to 200 2.8 without much trouble, I would like to reduce the number of lens to just a few. At times I carry a 105, 135 or 150 and 200 with a PZ 1P and with a second body SF1 with a wide like a 28 or 24, or just one body with 2 lens for travel + a DSLR. Right now I carry my SA9 with the 70 to 200 and a SD15 with a full frame 28 to 105. Just the sticker shock of the new Pentax lens, the last I time paid 2 grand for a body was my F3J in 1982 and I have never paid 2 grand for a lens, not even with inflation.
