There are other advantages to using a leader: abrassion resistance and the ability to break-off when needed.

I have this reel (Pinnacle Xihs) spooled with #50 Kanzen/ Tatsu #20 (3' to start with). The Tatsu is "left-over",

so if you are buying line just for leader, #20 Seaguar AbrazX will be fine.

The ability to break your line with a leader is huge. On the other hand with no leader and depending what you are using you can just bend hooks out and get your lure back.

14 or 16 lb fluoro

Braid with a leader is used to get the strength of the braid but the "invisibility" of the floro leader

 

i couldn't disagree more...the "strength" is only as strong as your knot and/or the leader you use.  you don't have 40lb strength when using 40lb braid and 20lb leader.

 

as for an "all around" line... i would go with a 10-12lb mono of your choice.  that leaves you open to top water (which fc does not) and that line strength doesn't limit the depth of cranks as a heavier line might and a good mono will hold up well enough for texas rigs, etc.  imo. 

I cant believe people are still commenting on this bahaha

Another vote for braid + leader
