Use what you have, I use the same #17 mono I run on my trolling reels. Also, if you'd like to try it. I have found painting my inlines black works better than any other painted inlines I have. And I have ALOT of inlines from 1/4oz up to 6 oz. Just like the black/purple mini disks work better than any other color I have. Jets is 50/50 on black vs other colors most days, but some days, black is the color to have.
