Which of these braided lines would you load onto a 2500 Shimano Nasci spinning reel?

 

15lb 4 strand 

or

20lb 8 strand

20lb, just because my old eyes have a hard time dealing with frog's hair especially if it is windy.

I still have 4 strand on my frog setup, but have moved to 8 strand on everything else.  I vote for the 20lb.

20 lb 8 strand, especially 832. Its slick and smooth, will go through the guides better. Add floro leader,  can't be beat.....

Either pound test but 8 strand all the way - my three Miravel 2500s have 20#, 15# and 10# 832 on them - all based on what techniques I'm using them for.
