Go play with the calculator. Increasing bar size .1 inches requires shortening the end length 2 inches to get the same gain! Bar size MOST CERTAINLY is the biggest factor in how stiff the bar is.
edit, here's the numbers I was using
Case 1: lets call this the base number...
A:12 inches
B:36 inches
C:12 inches (since your arm will be at a 90 degree angle to the bar in your "speed bar")
D: 1 inch
386 lb/in
-----------------------------------
Case 2: increase bar size 0.1 inches, others remain the same.
A:12 inches
B:36 inches
C:12 inches
D: 1.1 inch
565 lb/in
-----------------------------------
Case 3: in order to match Case 2's 0.1 increase to the original parameters you have to decrease A and C 2 inches.
A:10 inches
B:36 inches
C:10 inches
D: 1 inch
570 lb/in

I'm not trying to back you into a corner, but you really don't seem to know what you're talking about when it comes to sway bar calculations...
