Not impressed with Maxima ultragreen as mainline. Feels too stiff, too much memory, too thick.

I've used P-Line extensively and regarding 20lb test and up, all I can say is, "INCREDIBLE!" The stuff is so darn hard to break off that I've decided to drop down to 15lb mainline. Great thing about this line is since it's a copolymer, it's so thin that i can load up all 300yds of 15lb on an ambassador 6501 C3 if i chose to do so. Because of it's thin diameter, you can use a heavier mainline than you normally do.

In regards to line twist, based on my experience, there is no line that is immune. Use good quality swivels. And also make sure you spool on the line right!
