I had some B&W LB Speylines in use. They are similar to the Wulff lines and the Carrons. But they are much more expensive as the B&W lines.
As Mrs. Potter told me at the phone the lines are going to sold out because the linemaker not producing any more.
The coating of the B&W lines is very solid and it's able to smelt by using shrinktube and heathers.
For this low price a bargain.
