I'm reading through this thread wondering what rod you are using the Curado on. Especially when using light weights, I like to fish a rod that is fairly slow but with a faster tip. This seems to give you more casting control since the rod can load up easier and you don't have to toss it so hard. the fast tip keeps the "feel" of the rod.
I fish all Shimano reels too and have had the anti-reverse problem with Calcuttas twice. Now I only fish Curados....go figure
