Thank you very much Morten, kind words indeed.
Luckily I, like many others, found lots of help and advice here and on the UKG forum (we have some darn fine Armourers).
I'm grateful for the shoulders of giants.
When my kit arrived I'd looked at the 5 digit list and set my heart on one particular number. Closer to the end of my build I looked again and that one had been taken so I had to have a rethink.
I considered using my birth date but it didn't look visually appealing. I have always liked Ambigrams so I decided on something with a rotational symmetry.
Since Bill & Ted's Excellent "Sixty-Nine Dude!" makes me laugh (coupled with the fact I'm a bit of a cheeky chappie) the number I picked, and was subsequently issued with, fits me perfectly.
Si.
