A friend of mine got a Penn 320 gti (star drag) and 7' Penn Slammer for a christmas gift. Problem is choosing what to spool it with. He mainly fishes inshore for fluke, blues, bass, and occasionally cod on party boats. He needs a line that has little stretch for fluke and cod, but not braid, as braid seems to not go together well with jigging for blues and bass. ALSO, the 320 doesn't have that much capacity (330yds-20lb), so a low diameter line would be optimal for when the captain chooses a deep spot. Any opinions on a low diameter, medium stretch, mono line??? Something in the 30-40lb test range would work.
