while spider rigging i tie a 3-way swivel to main line, on the bottom i tie about 12-18" of line where i attach the weight. i use 1-3 oz weight depending on the speed and depth i need the bait. then of the other side of the swivel tie about 6-10" of line to tie my hook. you can really do it how you want. there is a lot of info on the internet about spider rigging. i use B n M trolling rods.and yes the weights will bend the rod over quite a bit. i like to have the rod tips 6 inches above the water.
