>"Going to states is a waste of time, by the time you have factored in VAT rebate it's not cheaper and people will look on you better if all your flying is in the theatre you operate in. Unless you want a holiday or to work out there."
That's rather an unfair blanket statement. Not everyone can afford UK hour building prices and a R44/B206 rating.
If you have no ties to the UK then going to the USA on a J1 visa can be the most attractive option to gain experience, plus it may open up other worldwide opportunities.
