Ageless, you are spot on. Not a day in the next ten for which rain is not forecasted. *sigh* Guess I'll plant my peas instead...
Dusty, I think I've decided on the more voluminous model. It looks more robust to me, not so soft shouldered. It also uses about the same amount of material for more space. Makes sense to me. Maybe I shouldn't get ahead of myself on the first build but the thought crossed my mind to do a subtle boat tail on the kitchen end. That whole bit would gently curve to about 6" narrower.
