A question, for what I dont know the answer.

Lets assume we have two perfect identical blanks,in matter of lenght,taper,wall thickness everything. The only difference between them will be just the material, one fiberglass and lets say the other high modulus carbon.
So my question is if we bend them until their tips will reach a certain point(same point for both) ...will they have the same action curve? The only difference will be just the power that is needed to reach the same curve? Or am I wrong.

Material has nothing to do with action. You can build a very fast action from bamboo, and a very slow action rod from graphite. You can build the same action from two different materials. You're not wrong.

Thank you Mr.Kirkman. I already learned from you and the great people around here that you can have an extra fast action blank made out of bamboo, fiberglass or whathever low modulus material or the opposite ,a very stiff rod/blank can have a slow or medium action....all is a matter of taper and wall thickness....but I was not sure about the answer for that particular question...although I guessed it may be correct.

And also im almost certain that a lot of people ( me included) will hesitate and will choose one or another before thinking

Good luck with the Expo Sir...wish I where there.

Another issue when looking at different materials is recovery rate and the related resonate frequency of rods using different materials. That is the problem with using the terms "fast" and "slow" when using a static test, such as used to measure the "action" of a rod. All imply movement, but action of a rod is a static measurement, i.e. how the rod bends under load. You could build rods from anything from greenheart to boron with exactly the same action, but you would have vastly different rods due to the recovery rate of the different material.

Right, Action is where the rod initially bends, not how quickly it reacts or recovers. Speed is the moniker for reaction and recovery, and rarely makes it into any sort of catalog specs.

Yes Sir you are right on spot with that...but I was interested only in the actual action of them..yes im aware there are some other very important properties of these materals such recovery time and wheight that will affect the behavior of the final rod..but again, I wasn't sure just about that particular question in my first post.

Thank you anyway for your answer.
