The 120lb leader is what we use for our twisted leaders for casting on charter. This leader material is just awesome.

Terminator leader material is not just the best value for money leader material we have found, it is amongst the best. This line has a hard shell, but is also soft enough to tie beautiful knots with.
This is the leader material used by Nomad Sportfishing on all charters, we use this and swear by it. Hundreds of people catch the fish of their life on this leader material each year, and the fact that we use and trust it, says a lot.

If you want the best casting and jigging leader, you need to be using Terminator monofilament.
