I regularly take the Chippy into 'strips', but I'm only aware of one that we visited this year which the CAA had officially declared 'difficult'. That was the DH Moth rally, Woburn Strip. It seemed no worse than many farm strips - tall trees and lakes to avoid, and (IIRC) 550m.
As for problamatic EFATOs, 09 at Barton offers limited choices. I had a partial EFATO last year - and it was off 09!
