I think it also depends on the type of jigging your doing. If your using light jigs that your letting out 200-250 feet, I think a fast action rod is ideal so that you can feel and work the jig with only the tip.
If your using a heavier jig, I agree with the slower action. I started using lightweight rods with the new Microwave Guide System and I can tell you...... it makes a huge difference.
Ideally.... you want both types of rods. The fast action when your fishing a 2oz jig far out and everybody else is fishing 4 or 5 ounces. The slower action when your more of a vertical angle with the heavier jig.
I have watched guys on head boats with 2 oz jigs and 100 yards of line out, crush fish while the rest of us using heavier jigs did nothing great. After 2 years of watching.... I started doing it myself.
