Data - sounds like you are taking on board some valuable lessons indeed. I too have had lots of experience flying around the 'big boys' but never actually felt any vortex - always allow plenty of time, and like Blinkz mentioned, try and stay above the approach of the aircraft in front, and land after their touchdown point - obviously only when practically possible.
I reckon I can be in the air by next weekend for a low level route flight - I will keep my fingers crossed.
I saw the first fallen conker today on the way to work - a bad sign that the wind and rain of autumn is on the way
