So I had to do a little test of my own. In all honesty I don't see how a Curado can be topped, or should I say Curado 100B because that's what I have. I have a couple more Curados on the way, and the Scorpion 1000. These low profile reels are all new to me as I've used Lew's BB-ING's for about the last 10 years but I am in love with the new generation of reels. The Clunn reels look decent and have fine results, only problem I have with BPS signature reels is they will probably be discontinued next year or some time in the future, then parts availability becomes an issue.
Parts are available for just about any model.
