I completely understand where you are coming from. I have a blad setup also and really prefer using a lighter simpler camera, for the style of work i use the blad for. I was looking into getting something like a fuji rangefinder or a rolleiflex. (I use a rolleicord also, as i really like TLRís) The blad is great and all but it just does not fit my style.
After saying all of that, i canít get rid of it, the images i produce with it are ones I am happy with.
