1) Light line is really a pussy way to fish when you think about it pulling on a 40 lb fish with 8lb of drag for an hour is like going to the gym and working with little dumbbells.
1a) 37 pound Albie on Sunday...over 150 yards of line out on a long soak with maybe 5 pounds of drag in less than 15 minutes. 40 pounder at 8 pounds of drag one hour??? Who's the pussy Justin? slap:
2) A true sportsman uses more difficult techniques and conserves the resource.
2a) I am offended that you would think I am not a true sportsman because of the line size I choose to fish with...just a little narrow minded of you don't you think?

Is it really more difficult to land a fish on 50 pound than on 15? I think not. What fun is there in winching in a fish on gear so heavy you barely get a bend in the rod? Heavy line is not a technique...it is heavy line.
3) The boats this weekend that had a few guys fishing the heavy caught more fish than the average, especially the bluefin. That stuff will eat heavy line and keep eating until the one guy gets bit on 10 lb and shuts it off.
My advice is to start heavy and then go light.
3a) Must be nice to be able to get on all 20 or so Sporties that were out there in one weekend. Could we please only speak from what we actually experienced ourselves, and not hearsay? Anyone that has pursued Blue Fin Tuna know these fish are line shy as any species can be on any given day...that's why so many people use the florocarbon, or go to lighter line so they can get bit. I have seen many days out there when the fish would not touch anything heavier than 20# line...sometimes 15#. With your theory on this with you soaking 40#, and not getting bit, and me catching my limit on 15# I guess it would be my fault the fish wouldn't bite your line, and we wouldn't be friends anymore.
4) But in the end you can fish what ever you want you are the paying customer, loosing fish on the light shit is better than not getting bit on the heavy for most people. For what it is worth this is my opinon what is yours?
4a) I think the "paying customer" part is significant considering your opinion. I am sure most people that make their living, full time or part time catching fish, and needing a good count to fill their boat would agree with most of your logic...and you do make a lot of good points I don't want to take anything away from that. You put a lot of good info out there, and food for thought. I'm just throwing out a few more things in the mix.
5) Notice I said heaviest line possible, not the heaviest line you own. in all honesty based on the conditions light line is needed to get your bait away from the boat especially with sluggish bait. For the most part I belive that 25-30 lb should be considered the median. forty is getting heavy and 20 is getting light this is for so cal offshore fishing. when fishing the kelp or bay the game is much different and fish what is needed based on the size bait you are fishing.
5a) The best statement in this thread. IMHO
