For all intents and purposes, Medium Fast and Moderate Fast rod actions are 'interchangeable' terms/meanings...right...? In other words, they represent the same action/concept regardless of manufacturer/brand...right...? Or are both terms supposed to represent different actions...? Kind of confused because I see both terms all the time on rods and yet I don't know if they are supposed to be the same action or are they supposed to be different where one is supposed to be slightly faster than the other.

 

On the other hand, even if both terms do mean the same thing in practice/theory, there will always be 'some differences' in action between different rod manufacturer's medium fast or moderate fast action just due to the nature of the rod manufacturing process/craft and the varying degrees of materials and equipment used. So in reality, moderate fast and medium fast actions are not a 'standard-ised' action and will differ somewhat between rod manufacturer's just like how rod strengths are not standard-ised and therefore one manufacturer's medium heavy could very well be another manufacturer's heavy...right...?

   Medium fast (written M/F) means Medium power and fast action. Moderate fast (written MF) is a description of action ONLY. So you could have a M/MF, or a MH/MF, or a H/MF rod.

   It wasn't always this way. Many years ago, before graphite, there were some descriptions of rods using "medium" for action (what we now call power) and "fast" for speed, (what we now call action).

   What makes this confusing is that some regions of the country still use this terminology, and some flycasting aficionados still use this terminology. So you need to be really, really careful; know who you're talking to and how they use the words.

   If you're confused, and someone says they have a medium action rod, just ask them, "What speed?".  If they say, "fast", you know where you stand.

   It won't happen all that often.                       jj

Right.
