Its all a moot point at the moment! As I said in another thread, I did a few quick calculations today and have realised that it'll probably be 18 months before I start this project. At least that will give me plenty of time to do plenty of research. It also means that I'll spend the next 18 months going more and more insane than I already am. I just can't wait to wake up one day and go out to the garage and spend 12 hours stripping my knuckles bare and using swear words that not even Quinten Tarantino has heard of.
