Hey BB,
I also think the wall and concrete path have had a big part to play in the lawn loss.
My front yard is predominantly North facing. I did expect a lot more hot weather than we've had also.
I had a couple of reasons for going with the bent at the front. Firstly I wasn't able to do any landscaping until April so I wasn't going to put SA down then. Also I really like the look of Bentgrass and fancied the challenge of getting it going and maintaining it. And as I has just gotten my Webb up and running, I wanted to be able to mow a lawn low in winter when my SA was going into dormancy. Also the fact that it only cost $90 for the seed meant I wasn't too worried if it failed (which it clearly has).
As I said in my earlier post I will try again with the Penn G2 in March and if by December it begins to die out then I'll go with SA at the front
