i was going over the internet the other day and found on a australian forum (i think) that they did a research among capts about this.
The results of top fighting fish were:
1-Swordfish
2-YFTuna
3-Black Marlin
4-Blue Marlin
I never caught a swordie or a giant tuna, but i know how hard the regular ones fight, so i can imagine how much of fight a 600# tuna would give
Marlin is definately more excepting but same weight the tuna might be tuffer to catch (maybe because they dont get tired jumping?)
