What is the Biggest Iron your carry?

[FairwayDodger]

I've been carrying my clubs over the winter so its a 4 iron. Once I go back to the trolley I'll probably put the 3 iron back in.... but realistically I rarely hit it in a competitive round; partly because my course is too short and partly because I don't seem able to hit it nowadays!

When I went to buy my new clubs there werent any that had bigger than a 5 iron.
