It's really hard to say what irons would be best for you. The thing I would recommend most would be to go to a major golf centre near you and try out lots of different types of iron sets. The other thing which might be good is if it's within your budget, get a fitting session.
A fitting session will help ensure you have or get the right flex of golf shaft as well as the right length for what you should be swinging. It will also help you get the proper lie angle on your clubs.
I have been looking at the Callaway Razrs because I have a friend that is considering purchasing a set. I have not personally swung any of them but from all the reviews I've read and the additional information they seem to be performing up to the expectations that have been set.
Hope this helps, I know it's probably a bit vague.
