did you spool up the line right ? if spooled wrong , you will have coils through out the line . try the braid , which has no memory (once the waxy coating has wore away ) see if that solves it . the coils will possibly cause line slap . like Mike said , 14 lb. line is awfully big for that size reel , most use 8 lb. max , if you do need stronger line , braid is your best choice used along with a leader of mono or flourocarbon . i would recommend 10-15 lb . that stuff if plenty strong , needing stronger line , you might consider a baitcasting set up
