I've been doing that as well, works well enough. The zone system really helped me in getting exactly what I wanted on the negative.
From earlier today. Only about a 3 stop dynamic range (minus the sky), so I reduced exposure and increased development from 8 minutes to 10:30 in order to increase the contrast and sense of texture.
Are you tray developing? I don't have an easy way of making a darkroom so I am using a Combi tank. I need to get my hands on some empty 4x5 boxes so I can separate the shots +1, -1 etc....
