Well now that I've played with these clubs a few times I'll give you my two cents:

LT stands for low trajectory, but in the hands of a capable golfer, this doesn't have to be the case. I can easily get these irons high in the air in a hurry if need be, but they do have a penetrating ball flight as well. If the OS irons are designed to get the ball in the air faster than the LT irons then they may be good for high handicap golfers, but they'd likely balloon on a better player.

These irons don't have the offset that the OS irons do and are more blade-like. The lack of an offset enables the player to work the ball relatively easily in comparison to the OSs. The LTs won't give you as much workability as a forged iron like the MBs would, but they are quite forgiving - as advertised.

All in all, I'd recommend these irons for a mid handicap golfer. Don't let the "low trajectory" moniker dissuade you from giving them a try.
