Cheers All, I'll start with the inner tube option and see how that
looks (as I have plenty spare in the garage), we have well over a year,
and the GF (is there a usnet shorting for fiancee? SWMBO I guess, but I
still have an option!) has a few months to pine whist I am out of the
country.

Hi David, the internet is a small place isn't it!
