No such thing as a heavy float/bobber to cast way out that will have super sensitivity. Either use a bait they will hold on to longer like a minnow or get ya a float tube. Slightly lighter line and a slightly heavier float with your bait closer to the float will increase casting distance a tad. Maybe a fly rod. I use really small floats and baits and have a hard time getting any real distance, im still very happy with how effective the rig is though. I dont spook fish with my casts and will catch anything that would nibble the bait.
