peregrines...........
I just got a hold of some SA Tarpon\Billfish leaders on eBay that I think may fit the bill.
They are 31" long fluorocarbon with a class section of 20 Lbs and a shock tippet of 80 Lbs.
From what I have heard, GT?s are not leader shy but require a fast moving popper to excite them into a bite.
I?ll let you know.
