Saying anything negative about this line genuinely feels unfair due to its seriously solid performance and incredibly low price in a notoriously pricey market. Seaguar Red Label offers a good degree of strength, low-stretch, durability and sensitivity, especially when you consider that it is around $10 cheaper than any of the other big players in the fluorocarbon space.
For the angler who is tired of spending big money on top of the range fluorocarbon lines or for the angler who is just getting started using fluorocarbon lines, Seaguar Red Label seems to be one of the few (if not the only) product out there that can offer truly good performance at a fair price.
A quick note, if you are currently using Berkley Vanish and are willing to increase your budget just a little bit, do yourself a favor and pick up Red Label. The performance boost will be more than worth it!
