As usual Downriggin has it right. I have 20# PowerPro on my Calcutta reel with Berkley Buzz Ramsey rod. It is a great combo for some things, but not for use in downriggers. June 1st I was out there with it and sure enough the line kept slipping out of the clip. I thought about buying a different clip style to counteract that, but have decided to keep my Calcutta combo for mootching and such and use my Penn with 20lb mono for the downrigger.
