I can definitely say my 9 footer casts longer than my 5-6 footers. But I think it would be even better if it had more backbone. Casting it is like casting a wet noodle. It can be done, but it's not very accurate. And I don't think it's as efficient either (as far as distance goes), compared in theory to one somewhat stiffer. But the flexibility is actually what attracted me to this one originally, so I'm not going to give it up. The long rod I had before that broke on the first decent fish (the bottom section at that!)! So I'll keep the wet noodle around, and hopefully add one that's more stout in the near future. I don't have any "tweener" rods (7-8 ft), at least not light action rods. Sorry I can't help you there.
