I got one about a week ago. I rarely stray from Airrus rods (and now possibly e21 Rods), but something about the look and review on this rod, I had to try it.
It's pretty darn special compared to what I'm used to. I got a similar model, 6'8" MH but XF blank. I'm completely impressed with the weight and balance compared to the power and action. On top of that, the handle and reel seat are very "state-of-the-art" and rival anything I've used. Airrus / Ken Whiting always led the pack in my opinion with the handle materials and proprietary reel seats, but the Cumara is right up there now.
It's a minimalistic approach for the best hands-on blank feel, combined with, to me, a great blank. I am not really sure where it lies as far as sensitivity. I've already caught several fish with it, mostly small two pounders or less, and that 3.5 I entered in the tournament. I think it's sensitive, but I need more time with it before I can compare it to my GLX.
If it didn't have an incredible warranty as well, I probably would have had a tough time buying one. Oh and that hook keeper - pretty cool, takes some time to get used to, but it's just a hook keeper, nothing that would make or break another purchase for me.
