In the suspension shootout between Herb Adams and Dick Gulstrand, Adams won the matchup with softer springs and the largest sway bars he could bend up. I believe they were 1 5/16 inch front, I can't recall the rear size.
For those of you that don't know who Herb Adams is, he was the suspension designer at Pontiac and designed the original suspension for the T/A. Dick Gulstrand was mostly noted for Corvette suspensions and his approach was stiff springs and small sway bars. In any published information Adams has always said large bars to control body roll and soft springs that more easily conform to road irregularities to keep the tires in contact with the road.
Here is a link to the thread talking about the shootout:

There are definitely two schools of thought about what makes a better handling 2nd Gen F body. In my own 73 T/A I followed Adams suggestions for a street driven autocross car and had great success with it winning the local SCCA championship for the year I ran the car.
There is a reference to another shootout that Ken Crocie refers to that I have never read, someone asked for a link to the article, but none was ever furnished.
