Between those two I like Seaguar the best. I tried Sunline Shooter once and it broke on me three times the first day I tried it. I don't have any issues with Seaguar Invizx. I also like P-Line Halo but it has a little more memory than Invizx.

I use the 15 pd floro coated pline..I think Premium CX .Nothing smaller than 15, i will use 20 for some applications..I use for Finesse plastics and believe it or not cranks. NO issues breaking on hook sets..However i tried some 10 once and experienced that [censored]..I think either brand you guys mentioned sunline or Seagar suppossed to be better, havent got around to it..Tight lines..
