Good stuff man, splashing out before training even starts, I like your style! My EP3 was a new job present to myself too, but at least I started my job first... What you doing with the RAF?
That Cobra should sound awesome, and you can't go wrong with a japcan hanging out the back, though your neighbours might not appreciate it. I'm aiming for something similar, try and put up a vid if you can, I'd love to hear it.
