Here is my opinion on line. Take it or leave it.
Use monofilament on spools.
Buy what is on sale. Technology has come along so that nearly all name brand lines will be very effective with their poundage. If your looking for High-Vis I really like Suffix in Bright Green, Red, and they might even make Orange.
Fluorocarbon - I see no use for this bass/panfishing. I have tried it bass fishing and get no less strikes on monofilament. TROUT/STEELHEAD on the other hand, are very particular and picky. I will always use a fluorocarbon leader for this and usually one spool will last me all season due to the fact I only use 4 foot at a time. I buy many different poundages due to the clarity of water.
So, is the adavantage worth the price difference?
Yes and no, because of my method of use. I only use a spool a season, but the fish don't know any difference and it keeps money in my pocket.
