Yep!
Seeing was pretty good, but Saturn was blurring in n out of focus at 217x.

no can do - the trip from my house to the backyard involves a narrow corridor, dog infested deck, 4 stairs and pomeranian crap covering the back courtyard

It sure was! 12" custom built dob with hand figured mirror, a complement of accessories, 600 bucks, the trap was set!
Optical performance does look great with my rough collimation, even at 400x I got nice tight stars but seeing was getting mushy. Omega Centauri was a plethora of pinpoints at 272x and Saturn very sharp in moments of good seeing. Comparing to views in my 10" from memory, I can say that the 10" is virtually just as sharp!
This saturday, forecast is for clear skies so I'm going to fiddle with the 12" collimation and have a showdown between both scopes
