15 or 20lb Flurocarbon for Snapper/Tuna?
Submitted by WODF on Mon, 2009-01-26 11:02
Probably a dumb question and not much point to it but what would you get? 15 or 20lb or both 
flurocarbon for chasing Snapper, Tuna and Queenies to 10kg? with 10-15lb braid if it makes a difference. Oh and why?
Advantages of 15lb compared to the 20lb - thinner in dia., casts easier through the guides, better knot strength?
Advantages of 20lb compared to the 15lb - stronger, more abrasion resistant,
So which would you choose?

i would go 20 just incase
i would go 20 just incase you hook something with teeths, and long fights with tuna wear down leader which may happen if you catch a 10kg tuna plus the chance of a bigger one. you can always shy down if your not getting the right distance or fewer bites though just take both

What's on the end?
I prefer to use thinner, more supple flourocarbon if I'm using something like soft plastics or small bibbed minnows. I find that heavier leader is stiffer and can negatively affect the action of the lure. With the other types of lures or bait, no problem with the heavier stuff.
If you're only using a metre or so of leader I don't see how casting distance is going to be affected and even if you're using a longer (wind on?) leader the difference between 15 and 20 lb is pretty small.
As flangies said, tuna dish out long fights, and snapper have tough abrasive teeth...so your leader has to be able to take a bit of punishment.
