There are many reasons to use heavy action rods with low stretch line and high speed reels while fishing jigs. 1) Most jigs are used (not always) in deeper water and jig hooks are notorious for allowing "quick" releases. It is all about the hookset, getting the fish up, and getting it to the boat as fast as possible. Fluorocarbon lines are my preferred line. A Chronarch will increase your catch. A stiff, sensitive 6'6" to 7' rod is a must. You do not want to allow the fish to fight. You want to get a good, hard hookset followed by a rapid "turning" of the fish. If you have a buggy whip it will allow the fish to jump or dive which turns the jighook in the fish's mouth and thus a "quick" release situation. Jigs have always been my preferred method for bassfishing. They are known for their big fish ability and it is well known that bass love their crawdaddies.
p.s. I sucked at the Open, had some bad luck. I have a bruised ego but I will be much better prepared for the next one. I should have thrown a jig!
