To be quite honest I can totally understand the suggestion of SLE from a superficial view, though from what I've read and observed I still think LSE makes the most sense.
The comparison to Hank Hill seems a bit odd to me since, from what I remember from watching the show back in the day, Hill was a rather calm, quiet, unambitious sort of guy, ESI is quite possible for him. Wayne, on the other hand, came across to me as being rather restless and full of balanced energy, pretty much of what I've observed from EJ's, especially Ni PoLR's.
I could make a longer argument for why I think so on another day if you're curious, though my heads working on another project atm and I don't feel that I conjure up enough
to make any sense right now either
