I see 3 types / Mfg / of 7 strand wire:
1. Malin Wire Line
2. Mason Multistrand Wire Line
3. Torpedo Wire
The Torpedo seems to be the lowest coast and advertises as follows;
Torpedo Wire is more flexible than other wire lines used for fishing. Crimps are not required, you can use normal fishing knots. Being more flexible than other wire lines, this wire line is less prone to kinking. Torpedo Wire is less prone to Spiny Water Fleas than some other wire lines. The diameter of torpedo wire is .015 inches and rated at 20, 30, or 45 lb test. Available colors are Bright Silver or Smoke.
What works best in the real world?
