Don't avoid using the curtain shutter and associated settings, they are a lot of fun to use and you can, with the aid of an inexpensive self made shutter tester and "Audacity" software, easily establish a chart of actual shutter speeds and match it up with your b&w developers.
That camera needs badly exercise, like any workhorse, and is a lot of fun to shoot hand held, as designed.
I used my speed graphic ani with the built in shutter and a barrel lens fully open at F4 (5.6?) to photograph some models long ago, and if I still did that sort of modeling photography, I'd still use the 4"x5" S.Graphic for some shots.
Have fun and enjoy your beautiful camera.
