Subject: [Leica] .85x and 75-135mm

I'm getting an M6 to go with a longer lens, either the 1.4 Summilux or the
CV 2.5 75mm Color-Heliar. Because of this, I'm considering the .85. Is this
the way to go, rather than the .72? Apart from the absence of the 28mm
frames (which I have on my MP-4), what are the disadvantages of the .85 of
any?

Thanks in advance
