Slim,
I did my initial Class I over 11 years ago 1995 (ECG) (aged 29), at Gatwick which was fine, renewed 96, went o/seas, 97, 98, came back, class II for a while, renewed JAR in 2001 (with ECG), did class II (CASA) in 2002, decided to take CPL recently hence the class I this week.
FYI, just spoke to the Doc, he has submitted the second ECG with the "within limits variant" and he is comfortable with it., however he still wants a stress test to be sure, he's 90% sure that there is nothing up, but wants the check anyway.
You guessed right about the ribs tho

, I has a badly bruised rib from a tackle when I did the class I at gatwick, and so had difficulty doing the chest expansion without pain
