Most sinker guides list the shapes and stop there. Egg, bullet, split shot, walking, no-roll. Then they tell you to use "just enough weight" and leave you to guess what that means in ounces. The guess is the hard part. A 1/8 oz weight that is perfect on a Texas rig in four feet of water is useless for a bottom bouncer in 30 feet, where the usual starting point is 3 oz.
So this page does both jobs. It ranks nine freshwater sinkers, one for each rig most anglers actually tie, and it puts a starting weight on every rig in the chart further down: which shape, how many ounces to begin with, and what should make you go heavier. The numbers are common starting points from bass and walleye anglers and guides, not laws. Wind, current and how fast you want the bait to fall all move them.
If you only buy one thing, buy a split-shot assortment and a box of 1/4 to 1/2 oz egg sinkers. That covers bobber fishing and bottom fishing in ponds and lakes. Add drop shot, tungsten and bottom-bouncer weights when you start fishing those rigs. Tom has not tested these sinkers.
