My 35 mm equipment spends most of its time off tripod. The larger stuff is just the opposite.
I use both as well. Whatever suits the job, or whatever camera I have with me.
i use leica R and M -- depends on the job and the mood -- traveling usually means the Leica CL for size and speed of use, but the Leicaflex is just pure sex to use, no two ways about it, and you need the reflex for tele and close-up shooting (or so I rationalize things.)
so, yes, keep the slr -- you will need both at time, if for no other reason that, if you sell it, you will later say "oh, I should have kept that."
