I actually really like #4, it's normally a good for me to win a hole in MP, for some reason I seem to get a birdie there more often than not. I have noticed that my irons have made a huge difference though. I usually play my first right up to the edge of the rough,you will find that there is a slight uphill just before the rough so many times when you look like you've over hit it, it will still stop on the fairway(not always though, sometimes you do simply play it to hard, which makes the spin on the second very difficult). The wind obviously determines how I play the second, but if you have high trajectory irons then go for the pin with full bs, I'm not kidding when I say I usually leave it 1 or 2 ft from the pin.
I currently have the burners and before them the lvl 58 G10's and both irons produced the same result, again cause of the trajectory(VERY IMPORTANT), before either of the sets of clubs I would agree that it is almost impossible to get close, simply cause you can't get the ball to stop.
Well I will stop rambling on about this :-), hope this helps and GL.
