I started using a carolina rig in the lower Niagara, bouncing soft plastics off bottom with decent success for smallies. I had bought some 1/4 oz bullett weights and started out with 1 on. Not enough weight so I added a 2nd one. My question is, is this an " acceptable" way to add weight, or am I missing out on some benefit by not switching to a single 1/2 oz weight?
