something funny has happened - my last post seems to have disappeared. Of course, I might have done something stupid seeing I have mod access.
My last post stated that if the concern Mark had was that there wasn't enough flexibility with a split ring, he could consider using two split rings instead of one.
Cam - there is nothing unusual in going with two split rings. It is quite common for barra fisherman to do this. One fo the problems with using a single ring with GTs is when the fish hooks up with both trebles. At certain angles, the fish can exert direct pressure onto the hook or the ring and this is what causes a failure in your terminals. Big GTs can exert an amazing amount of pressure onto your terminals. If you use two rings, there is a lot more flexibility and length, not unlike if you used an assist cord.
if you have fished for GTs a lot before, you'd have experienced that a hookup with a treble is never 100% and that it is not unusual to lose a fish even after quite a long fight when the hook drops out. On the other hand, it is rare for this to happen with a single, particularly if attached with an assist
