Which Camera?

As I get ready for a busy holiday season of photography I’m also thinking about what I want to do afterwards in early next year.  I’m currently thinking about more B&W photography, but not exclusively, and doing it in cold, wet weather.  As I think about it, I have been playing around to see what I can do with my waterproof pocket Ricoh WG-60 camera.  I like the camera but it is limited in what it can do and I would like to try some longer exposure photography which is something I have never done.  Just the thought of needing to carry around a tripod has turned me off in the past, but as a minimum I would like a camera with decent image quality, good image stabilization for very slow shutter speeds, a zoom lens with wide and long enough reach, the ability to photograph in manual mode, smallish and light in weight, and that is weather resistant.

I could use my X-H1 camera with the 18-135mm lens, but it is on the large and heavy side, so I’m wondering if there isn’t a better compromise.  I would also like a pocket camera but that really limits my possibilities.  I could get another small camera like one of the Sony RX100 series but none of them meet all of my wishes and they aren’t very rugged or weather resistant.  That leaves me thinking about possibilities between the RX100s and the X-H1, as well as, will I do enough photography to warrant getting another camera?  Would an additional camera significantly increase my picture making opportunities?  Would I be more likely to carry another camera with me at all times, in all weather conditions and what camera would that be?  And the hardest question to answer, where would I go to find compositions?
