Callaway has challenged us golfers to keep its new seven-model iron family straight.
mosnas, any chance you hit the Razr X HLs? It has red trim similar to the Razr X Black, but is built like the first cousin of the Diablo Edge irons.
This Callaway site contains a Razr X family video so 'Trappers can figure out who's who:

The Black model falls between the Razr X (center of the family's universe) and Razr X Tour. Black has the same loft combinations as the Razr X, but has less offset and a slightly narrower head. The Black head design has a back weight bar from behind center to the heel. This is heel weighting which would cause the low-offset clubface to close more quickly - the benefits of offset without the look. Someone described Black it as an SGI iron with a tour setup.
I sampled the Razr X family at a regional demo day a couple of weeks ago. I hit the Razr X and the Black with a couple of different R-flex shaft combinations each, and the Razr X Tour in a couple of set stiff-flex clubs. The Razr X felt like a crisper version of the X20, which served me well for two seasons. The Black hit the ball OK, but had a somewhat strange feel to it. But, I like the idea of a low offset SGI club if it would deliver good shots.
I am redoing my bag, and just had a local fitting done on Razr X irons. I tried the Blacks again, but the Razr X delivered better launch-monitor data and better feel. Not sure whether to get the Razr X, or put lighter shafts into my X20 Tours.
