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.
