Sensitivity

[snowplow]

Just curious, if you have a heavy, medium, and light action rod of the same make (blank) and action, as you get lighter, will it get more sensitive? Or is that only a factor of blank material? 

 

Or if it helps, you could say it this way. Take the St Croix victory rod line for instance. Are they all the same sensitivity regardless of power and action?

Every rod is going to have a different feel to it, even if just minimal.

If you ever had a rod break at the top and cut a few inches off and glued a new top guide on the rod would feel completely different, so a shorter rod/longer will have a different feel to it, even if just an inch or 2.

 

And for different rod powers and actions, they have to make the rod bend in a different area, that can affect it quite a bit, and for the power they have to make the rod stronger/weaker, thicker/thinner.

 

Quality rod, made with quality material, paired with the right line (braid/fluoro) will give you the best sensitivity.

 

Im no rod expert or builder, im just someone who has dozens of rods and this is what ive learned about fishing them, even ones from the same brand and model line.

 

Best way to find out about the St Croix's are to call their customer service and ask them, they will have all the answers.

Lots of factors when it comes to sensitive.  Within the blank, a graphite scrim will create a more sensitive blank than that of a fiberglass scrim.   

Sorry, scrim is the material that is applied to bottom side (mandrel side) of the graphite sheet.  The scrim holds together the graphite fibers so they do not separate when rolled under pressure.

Gary Loomis was the first to introduce graphite scrim in the GLX series of rods.

Or was it the IMX????

 I think it was the IMX that was the top of the line when it was introduced. GLX came several years later.

A heavy action rod should have a higher moment of inertia which is a measure of an object's resistance to changes in its rotation about an axis. It depends on the mass distribution of the object relative to the axis of rotation.  A higher moment of inertia has to make a rod less sensitive since it will take more force to move the rod.  I don’t know if anyone can detect the slight difference in moment of inertia between two rods but it’s the only aspect of sensitivity I’ve heard of that can be explained with physics.

I don't understand the question? A bite is a bite. Then again I use braid to leader on everything so I can feel a bite on almost anything I fish. I would say depends on what you're fishing bait and weight wise.

Same blank, same taper, the lighter action rod will give you a better feel.

Lighter rod = more feel

Stiffer rod = more feel

Longer rod = more feel

Lighter action therefore may or may not.
