1) I would like to take the left side out of play 2) If the greatest ball striker of all time used 5 degree open clubs, I would like to try them. Everyone should want to try them. SOMEONE SHOULD MAKE THEM. I cant understand why it would be soooo hard to accomplish this.
The solution to taking the left side out of play should not be opening your clubs 5 degrees. Furthermore, the bounce and grind of your irons were not designed to sit this open. You could rotate the clubhead on the shaft (or grip for a near identical effect) but they wont sit naturally at address like this at all.
I'd talk to a pro about your swingpath and impact mechanics before you do something like this.
Ben Hogan did grind his clubs to a negative bounce: while the solution to taking the left side out of play does not lie soley in one place, certainly it was a piece of what made hogans fade so great. I can hit a fade, but am after a specific type fade: the ben hogan fade.
Ben would tell you to go hit 10,000 balls.
