You can use just about any kind of line...but you must take into consideration two factors...
1.) Line Diameter - you need a line that is thick enough so the adjustment cleat holds it without slipping.
2.) SWL (Safe Working Load) - Strong enough not to break and cause depth charging.
The small blocks incorporated into the adjustable trap lines will help eliminate line chaffing and abrasion...which could also lead to depth charging. The stock Tiger system works well for this.
Personally, I use 3/16" Dyneema for all my trap lines.
