Like I said, I'm not going to spend any more time on the barometer thing. My uneducated opinion is, if you are in fish and your speed, presentation, color, and depth is right you will probably catch fish. If the barometer is in a 29.7 to31.1 you will get more bites that bend the poles under the boat and on high presure you will see more ticks on the rod tips. You will still have some of both with either system.
