Assumption is that OP wants high res and low grain in a light weight rig... may be jumping too fast. Grain can be like a "pop" on a recording and adds some life to an otherwise overly smooth (almost like cake icing) digital image. Won't tell you what to like and what not to, but there is more variety out there.... though current "style" seems to favor grainless. Been there, done that, and moved on... maybe as you are doing now. BTW, I like to print big 'cause it pushes the skill curve out as well as highlights what you've really got... a useful exercise of its own. One of the skills not talked about much is simply "editting"... picking which shots are the real keepers. That said, I find "small" has its virtues, too.
Lots of stuff for which 35mm may actually prove optimal relative to larger formats. I ponder the same thing, but MF is a whole way of life different that for now, I am resisting without much system stress. "Resistance is NOT futile!" Agree with the tripod thing, but especially with exhausting every option within the gear you have, and only reluctantly switching. I find every camera hop involves a bit of time to get comfortable and back under control. Done a bunch of that over the last few years - and not proud of it btw. Althought there is a circular staircase perhaps, it feels increasingly as if there's too much time wasted in shooting while you get back into gear with new "stuff". My current biggest dis-suader keeping G.A.S. at bay.
+1 to the Rangefinder for easily managed, razor sharp focus without a digital "live view" focus (magnification) assistance. My aging eyes can manage the RF without much assistance, but an SLR has put me back in the hunt for diopter adjustments, and while the tripod may part of the answer and shutter speed another, it's eliminating one variable at a time.
