"Yep I'm a lefty. Over the past 4 years i have slowly been buying the Calais reels to replace my others. They are very costly but think they are worth it. Now have 6 of these. "

"Smooth, solid, superb, and slick looking as well they should for what they cost. I have Calcutta TE-GT's, Daiwa Steez reels and the Calais is best overall reel I've used. They are comfortable and an absolute pleasure to use."
