LOFT FOR LOFT, which of your iron heads flies highest?  Which spins most?

I am open to everything from TS4 to M980.  I currently play TS2.  I’m a ball-first sweeper.  Stopping power is poor for me at 70 ish MPH.  I realize that comes with the low swing speed but I could do with more height and/or spin.

I know about loft, shafts, and choice of ball.  But what can the iron head design get me?  Thanks.
