I fish mostly in lakes for trout and bass.
Sensitivity is critical to my fishing.
I'm sure that the vast majority of modern graphite rods are amazingly sensitive. Whether or not you 'feel' the take through the line or the rod would have a few variables; line angle to the tip, density of the line, depth of the line in the water, current, etc.
The important thing is that you do feel or somehow perceive the take. If you aren't feeling anything until the line is pulled strongly, you are likely missing LOTS of fish.
