Spike, What method are you using? Do you use live baits, cutlets, fillets, spinners etc? Have you perhaps ever watched movie footage of how Tigerfgish feed? They usually attack the bait, and scale it as they swim away from other competition at high speed. They then stop and turn the bait around and then swallow. What worked for me when using cutlets, fillets and live baits was to wait until the first run was done, wait a coupla seconds more and then as the fish moved again, strike as hard as you can. We use chemically sharpened Gamagatsu type hooks. We never did have too much luck with circle hooks though I know of some who have! Using rapalas is tough because they have such hard mouths! The other thing we found was that the trace/leader wire had to be 40lb bs+ and of the braided cable type to prevent the Tiger from kinking it and breaking it. Brings back such great memories just writing about it! Fly fishing for them is awesome but requires heaps of patience!
