Berkley Vanish is a great product if you want to experience the key benefits of fluorocarbon line without breaking the bank. The product boasts solid strength and knot tying ability as well as very low visibility underwater, all very important traits when looking for a good fluorocarbon line. However, this line does come with some challenges as it has fairly high memory and becomes brittle quickly when there is a kink or knick in the line.
The best use case for Berkley Vanish is as a leader material or a mainline on a baitcasting reel. We do not recommend using this line as a mainline on spinning gear due to its memory and tendency to twist.
If you are looking for a solid, affordable fluorocarbon, give Berkley vanish a go. If you want something that offers premium degrees of strength, suppleness and durability and have a bit of budget, you would be better off going for something in the Berkley Trilene series or Seaguar InvizX.
