This discussion serves to point out a couple of contrasts. It was correctly pointed out that Captains and crew have somewhat different perspectives than some anglers. They want/need to report good catch numbers. Anglers also want to catch fish, but also want to hook fish. The next question is what is 130#? Not all brands have the same breaking strength. Same with 100#. I've come to think that abrasion resistance is probably more important than the difference between two line tests. And is breaking strength even an issue? Unless your drag seizes, you can't break 100# (more on that below). I'd wager that more big fish are lost because of either failed connections or prolonged abrasion from teeth. I won't fish sardines with any heavier fluoro than 100# because I want the bait to swim well, and more importantly want to get bit more frequently. I still get my share of cows. Do I go heavier with other baits like skippies----absolutely, but that's another issue. Here's something to try--- rig an outfit with a 100# fluoro topshot and whatever hook you prefer. Attach the hook to something immobile like a tree, a volkswagon, or whatever and then start pulling on it with your normal drag setting. Hint: you're not going to break the line. You can't break the line. Do it for a half hour or more and you'll have the same result. That's why we fish with reels that have drags. Now occasionally you encounter a fish that simply will not let itself be stopped, and for those fish it matters very little whether you're fishing 100# or 130#------you'll still have to go to a backup. That's just the thrill of fishing. Just me personally, I'd rather catch more fish, including some cows like I mentioned above, than fewer fish just on the one-in-a-million chance of hooking a 350# fish. And if that big one comes along, I'd love to do battle with my 100#, even if I lost.
