I think it is really situational. While lighter can sometimes be better, say when pitching jigs in shallow, I tend to go heavier more times than not. I can't seem to fish without some sort of feel and if the wind is up or there is current I opt for more weight. I spent a ton of time jigging last fall in the 26-30' range and had a 3/8 oz jig on all the time. Right below the boat even in the wind with good feel all the time. With bouncers, shallow stuff less than 10' I use 3/4 oz. unless it is windy. But, as depth and/or wind increase, weight goes up quickly. I don't like dragging a 2 oz. bouncer but some days it's how I do best.
