yes green is a pretty wide term,, I am sure if you rough out the staves,,, it will get below 20% pretty quick,, at that point putting the wood in low humidity,, or maybe low heat box,,,you could start working on your bow sooner than most would think,,, yes I think the slower and more patient is optimum,, that being said I have made some very nice bows working on a green stave to floor tiller,,,and a matter of weeks to getting it strung and shooting,, just depends on what you want to do,,,,
