Hey Alex, sorry we didn't get to meet up...maybe in October?
Peter, thanks but I'd like to avoid lift-outs. I don't like them due to the scenic discontinuity they create. I am intrigued by the around-the-walls approach but it will be a tough sell due to loss of floor space for other things. The L shape is such a clean package and presents itself well with a 30'+ front.
I should also mention that I'd like to stick with my Atlas investment and don't want curves under 99" diameter on the mains (planning for 108" if/when Atlas sees fit to deliver).
