I don't wear glasses and I think that is key. To be honest, I'm not a great framer. I have both 0.72 and 0.85 mag cameras, and use the 0.85 for lenses =>50mm, and the 0.72 for lenses =<35mm.
I usually use the 0.72 for my 35, when I said "all the time" up in my previous post what I really meant was that if I need to use the 0.85 for a 35mm lens I have no trouble at all using it on that camera. The reason that lens is on the 0.85 at the moment is that I am trying to finish a roll of film in it. But I do generally use it on the 0.72 because I like to see what's going on outside the framelines.
If you don't wear glasses, and if you don't care what's going on outside the frameslines at 35mm (since you apparently use it so little) then I would say consider a 0.85 mag camera. However a 0.72 mag also suits both lenses well.
I'm sure you know that Leica now only makes 0.72 mag cameras and that if you want either a 0.58 mag or a 0.85 mag body it is either the custom (Leica a la carte) route or used.
