For me people do get hung up on the Test curve and not the action of the rod as this is where the main characteristics of the rod are and its down to personnel choice.
I prefer a through action rod as I like the rod to act like a big long spring and if the fish decides to make that last lunge the rod (I feel) has the forgiving nature to cope with this as appose to a tip action where the “spring” is only in the top 25% of the rod.
I’ve fished with a good friend for 18 years had he prefers a tip action rod as he feels the back bone of a tip action rod give him that edge to put more pressure on the fish to “win the fight”.
His typical one liner when he comes to net my fish is “Bloody ell Pete next time I’m in the supermarket I’ll get you a new banana cost the one you’ve got in your hand would be banned by the E.U its too bent!!!” my reply is “go and stick that poker you fish with up ya bum!”
To me action is more important than T.C

But the best advise is what the other guys have said go and try your mates or have a play with a few in the tackle shops
