As Garry has suggested, power pro is excellent line. I've got it on all my baitcasters and one spinning rod.
I find most mono lines to be comparable but I've been using the Bass Pro brand lately as you can usually pick up larger quantities for a good price. Their brand of braid isn't bad either.
Another tip, when you're putting on new mono line, run it under warm water for a couple of minutes. This will help reduce memory.
Good luck.
