Sensitivity depends on a lot of things. The rod, if it is too stiff or limber, the line, mono has a lot of stretch, and reel. If all are matched up, you will be able to detect the slightest pick up. That is why one rod and reel are not used for all types of fishing. Finesse, bottom, top, worms, tubes, etc. can be fished with one set up, but you will be more seccessful if you have different setups for the type of fishing you are doing.
