A:
These rods are very similar in power and action to St. Croix Rods.
There's really no quantifiable way to measure sensitivity even though most people will try to tell you they know one rod os more sensitive than another. Given that point of view, I beleive the most sensitive rod can only be defined my the stiffest rod you can get in the lightest weight.
These rods are very stiff for their weight, they should be as sensitive as any other rod in their price range all the way up to $150 class rods.
