Might be interesting to have Nick J's "thoughts and comments" as a first time poster.
My thoughts are that if someone feels irresponsible enough to do an aero manouvreat low level in a built up area, then they can't be that responsible, a bit like the guy I saw doing aeros above a very busy Leicester airfield some years ago, then cutting up another GA on approach because he was in a sportier craft!
I'm no prude, but this is what gives GA a bad name imo.
Around Barton you are not in the "Low Level Route" and the airspace there has a base of 2000ft. Exactly how far and in what direction do you live from Barton ?
I live approx 12 miles SW of Barton
