looks like that RPLXi 5pc has a lot of "reserve power in the butt". I like the way the tip (which is only good for casting anyway) folds away so you can really put it to the fish during the fight. The Xi 5pc was really a ground breaking design.
I can only add that the 3PC #11 RPLXi was actually a very good tarpon rod. Soft enough to get a cast off quickly (and in close) and just about unbreakable. A tremendous fish fighter once you trusted it. I like the way the Xi2 casts much better (maybe it is not as strong?), but the Xi was a good rod. Very different.
It is funny, because there seems to be no evolution between the RPLX (a beast), the RPLXi (kinda sweet) and the Xi2 (crisp and sporty). Three different rods.
The other companies coppied the old actions (for good or bad). Winston XTR was very similar to the RPLX and the Scott S3 is (was) similar to the RPLXi. Chasing tails.
One cast can change your day...maybe your life.
