Thanks for the info spaw and I apologise for the drift. Last side track from me... I'm getting a bit more interest in F1 this year as things seem a bit more open. I hate it when one car seems too dominant. I still wonder what would have happened if Michael Schumacher (IMO by far the best current F1 driver) had the Williams a few years back when they were so dominant as I always felt it was his skill making lesser cars at least competitive.
