Can anyone explain the physics behind this?..in my mind a fast taper rod gives you more leverage..but I do understand if a rod is bent to its test curve then your putting any excess pressure on the fish.

Think of the rod butt handle as the pivot point. A through action rod will be shorter than a fast taper when compressed to its test curve so requires less pull on the second handle to exert the same force down the line.
Putting it another way, the fish has a shorter lever with a through action so cannot exert so much force on your second handle.

Just remember that the lever is working in the fishes favour, so the shorter the lever the more of your effort is transferred.

Test curve doesn't mean a great deal tbh, as it only rates the tip. Faster actioned rods like the hi s, you could chop a few inches off the tip and nearly double the tc. I like low tc, semi fast action rods that maintain a level of elasticity in the butt when the rod is bent to extremes, from brief experience the hi s 2.5 didn't quite match that criteria but I'd still favour them in the op's situation. If your taking a backup set anyway it doest matter much if you don't feel comfortable with them really.

What I've found over the years is most people like to feel that the rod has a lot more to give, even after being shown a bendy rod pulls a lot harder, and that to actually use that 'power in reserve' on a stiff rod the effort would be extreme

Problem is our tackle manufacturer fashionistas set what is popular.

50mm butt eyes on 2.75lb test curve rods, then 3.5lb tc, or 8ft short rods.

I believe that it was Richard Walker and his friends who came out with the concept of 11 and 12ft rods for carp fishing, because they found it the best length. We have surely moved on and forgotten.

I've landed fish to 34lb on 2.75lb TC rods from just out from the tip, to 150metres out and never did I feel that I was struggling.

This test curve rating, the weight required to pull the rod tip to an angle of 90⁰ could actually be photographed and used to show the action. You will see if a rod is tip or through action, because obvious it may sound, the fast taper tip action will be at the tip only, compared to all the way through.

The heavier test curve faster tip action is required for casting distance, that does not mean it is better for playing fish on.

"Problem is our tackle manufacturer fashionistas set what is popular" 100%!!!
I feel so sorry for people who have started in the last 10-15yrs, as now almost all easily obtained carp fishing information comes from commercial sources.
On the rod front I feel things have got so ridiculous that I have had to start putting them together myself just to get something sensible, my completed stalky type rod will fit clean through the centre of a 50mm butt guide!

To the OP.
If you really want to find out whats what with your rods when it comes to fish playing power I would strongly suggest that you try some deadlifts with them. I DO NOT MEAN lifting weights straight off the floor!! I do it using a pulley & weights and hold the rod flat so the curve in the rod and line angle can be easily observed.
Testing rods like this has been a MASSIVE eye opener and has totally changed how I view some of my rods and what they are suitable for. Having done a bit of it I can honestly say that until I do a good heavy deadlift on a rod, I have no idea how it will perform. Testing a rod like this also lets you feel how forgiving the butt section is under stress, by gently bouncing the weight you can feel for any little "lock ups" in the action.

Good video 👍🏻 Im not sure what tests christian who posted earlier was doing to get his results mind.
Are you sure?

This action cannot be undone.

Yes, continue
