I'm giving the Wishon Sterling set a proper trial presently. Results have been exceptional so far. They're still long irons because they're the irons I use to hit the ball longer.
The 4/5/6/7 have high COR faces to make up for being shorter than their standard length counterparts. So far for me I haven't seen any reason to think that this doesn't work. I still get good height and fantastic distance.
It's hard to imagine how awesome it is for every club to feel exactly the same - same weight, same length, same ball position. I am really digging it so far.
You need some swing speed to make the lower lofted irons work - the high COR face can only do so much. That's the drawback if there is one.
