Thanks for your views on this, I haven't been thinking about how Yukon will affect this.

The more I look into it the more I think the 2000 would be more appropriate for my current work and I am guessing that a lot of what I learn on 2000 can be taken to 2003 anyway, so I won't be starting from scratch if I do take 2003 at a later date.

I will probably regret this when it comes to taking the 2003 exam but I guess it gives me something to aim for in the future...
