my 2 cents. After years of trying them all, I have been using 12 lb Big Game for 50% of my fishing, 15 lb maxima green for topwater, spinnerbaits, buzzers, rattle trap type baits, and Viscous 15lb flouro for finesse jigs because of the sensitivity(improved clinch knot, but spit on it before snugging it down). Spinning reels, 8lb mono, I use a generic brand (drag set light), and for ultra light 4 or 2 lb test mono. I am 55 years old, and have caught more fish in the last 4 years than the 10 prior using this agenda. After I went to this agenda, no more unexplained break offs, with using mono for the most part when I need a new bulk spool of line I don't need to refinance the house to get it. By the way, keep all of your line out of direct light as much as possible. Keep the bulk spools in a drawer, and put the rods you used in a day of fishing away in the rod box or closest when you get home.
