Me too. I'm 6'2", and not what one would even passingly refer to as thin, and had a choice between E+ middle (6B) or E- aisle on an A320 SFO-PHL a couple of months ago. The RCC agent looked at me like I was crazy when I said I'd take the middle seat, but I found that it was as comfortable as I was going get. E- is murder on my legs.

For the record, it wasn't bad at all. Not great either, of course, but not bad.
