I think, tim, it's I druther, not I'd druther. Least ways that the way folks say it round here!
If we all wrote things the way we said them, why I think there'd be a whole mess of confusion round here! Some of us fine country folk would confuse the tar out of them city boys.
Ok, I'll go back to writing more or less in standard English now...
I think personally that hardwoods should only be worked green, else wise they get too hard and therefore working them is ore expensive to the client.
I don't have a lot of experience in softwoods, but my woodworking experience has taught me that often times these woods can actually be easier to work dry. however, I think the most important thing is the time constraints.
If you are felling your own trees i think it would be good to follow the old time schedule.
Fell the trees in the winter (under the waning or new moon, when they have no frost on them)
Hew the timbers in the first part of the spring or the late of the winter (again under the waning moon)
Now it's time to cut your joinery, which should take most of the summer on an average job. If you know a job will take more than 1 season (a working season, not a season of the year) to complete, fell and hew only that timber which you can use before the coming of the next winter.
Now in a modern setting you may not want to work that way. If you buy your timber from a supplier, just use it as it arrives and you should be fine. the trick is in attaching the other things to the frame in such a way as to account for shrinkage and settling.
