I’m of the opinion that it doesn’t really matter. I have tried all kinds even the cheapest stuff on amazon. The cheapest stuff is worthless. Other than that any name brand stuff is pretty good. I found a huge spool of spider 30# in green. I have spooled every reel I have with it with a 20# mono backer. It’s been 3 years on some of them. I just cut about 50’ off each season and put a new snap swivel. Everything will be close enough the trolling app will be within a foot of line. I pull everything on the same rods.
