Taking them down to floor tiller stage will help them dry quicker. Depending on how wet and the type of wood you may need to clamp to a form to prevent twisting as it dries. I would start with one or two, floor tiller green(no problem of over stressing)and set them aside for a month. Once you start working on tillering you will be able to tell how dry it is by the sound and feel of the wood and whether it is crisp or sluggish when recovering from bending. If it feels sluggish give it a few more weeks.
If all this works out, do a few more. Be sure it will work well before you commit all the staves. By next winter all your staves will be ready to work. If you rush any part of bow building you are setting yourself up for trouble.
