You guys had funky science teachers. So a steel ball that weighs 10,000 lbs. has the same density as a steel ship that weighs 10,000 lbs. yet one sinks and the other doesn't. Weird, because they have the same density, volume, and mass. Seriously, though you can't simply mix and match concepts to suit your argument. I have no clue what any of this has to do with the bullet weight on my Texas rig and the fish (that's bigger than yours :P) that's on the hook. A fish is incapable of determining the difference between a 1/8 oz. and 3/4 oz. bullet weight and the any angler that says they didn't get bit because they used the wrong weight is fooling themselves. If you got bit using 1/2 oz. tungsten and then no bites using 1/2 oz. lead, I'm going to tell you this: it wasn't the weight. I mean, probably, maybe, or not. Profile, fall rate, and the action of the bait is all influenced by what weight you choose. Most importantly, where you put that bait is the key factor in getting bit.
