It's time for me to re-string my Musky rigs. I'm looking at getting either 50 lb PowerPro (Red) or 50 lb Fireline (Flame Green). Any thoughts/comments/experiences with these lines? Also, does the color of musky line make a difference?

Is there a third, better option which I have not mentioned? I have read reviews saying that the PP is better due to the fact that it is round. Apparently Fireline is more flat...?

Thanks a lot.
