Cleveland irons are very underrated - Cleveland clubs in general are underrated.
The CG7 is as good a Game Improvement iron as any.
You'll not go far wrong with them.
The CG7's won a gold award in a rival mag last year. I really like the look of the black pearl edition and they are an iron I am considering next to AP1's and MX200(Second hand of course)
Just opened a set that came from the bay. look pretty good - £125 for 4 to pw, so you can find out how you like them without breaking the bank.
Incidentally, golfbidder have a number in stock at (what for them) look like pretty good prices. They are pretty much the only irons I've seen on the site which are comparable to ebay for prices.
If you're more patient than me, I'm sure you'll pick up a set of these (or their immediate predecessors/descendents) for less than £100 in good nick. Me, I just wanted to get the chance to try them before the weather breaks....
