I recently bought some invizx. Haven't tried it out yet ,but does it have good abrasion resistance and sensitivity? That's about all I need from fluoro. Are there any lines better for this?

Invizx rocks. I use 6# test among rip rap. No abrasion problems. If this is your 1st fc line and you are like me, you will not see a need to try other lines. As for sensitivity I think it better than mono of the same test. Excellent choice! 8-)
