Yeah, I remember all that stuff...I had a C/L aerobatics flyer tell me very earnestly that he incorporated around a 1/32 slop at the trailing edge of his carefully contoured, 1/32 thinner elevator to minimise the tiny bobble made by his hand exiting a manoeuver to S&L. Then, on TV last nite a full size aerobatic pilot showing off the full trailing edge strip aileron of his Edge/Extra/Giles, don't remember which, and it had a square, sharp cornered T/E at least 1/2 inch thick...
