Thanks for the PM jonathang,
I consider myself suitably bollocked for my outrageous posts
No I don't think I'm smarter than the average, and sorry you took offence at my posting, which was a lighthearted attempt to put some chill into someone who's obviously suffering from so much stress.....
Why don't you use Fly Stimulators' Reciprocal Heading Practice Engine?
All the best
