Hey Darryl,
That white collar reference wasn't for me was it?
I'll have you know that I don't wear collars, but open neck shirts thank you
The reason for my suggestion is that I know an old guy on the north side (Bracken ridge to be exact) who has all the bits but hasn't been able to put them all together as yet
May be you could practice on his first then your's would be a breeze.
Les - Do you really have a Cobra or is it just an illusion?
