First of all, dak4n, the Ping G and Callaway X20/X22 and Big Berthas were SGI (using the Golf Digest Hotlist categories).

EJ... Have you actually hit any irons from the Callaway X-series family? From your silly remarks, I doubt that you have.
The X20 had a fairly thick sole. I played it for about two years, then switched to X20 Tour to get a smaller clubhead, minimal offset and better feel.
The X.Forged (circa 2009) was a player's cavity. I tried to hit a couple of different versions with 5.5 and S300 shafts, and just couldn't get the ball airborne. So, it has a thin topline, but a player's cavity head design.
In 2012, Callaway served up 7 different RazrX iron models to choose from.
dak4n and EJ, I want to tell you this "in family" before you hear it from the cruel kids out on the street. You both suffer from topline neurosis, a mild miscognition which makes you think you are a purer golfer and eventually better golfer if you play muscleback irons.
For your info, Ernie Els won a tournament playing Big Bertha irons (though not with stock shafts), and Rocco Mediate won a tournament playing X22s. These are very high in SGI category.
