I have two...
my fav all around is:
Quantum Catalyst spinning reel on a St. Croix Avid 5'6 UL
Yozuri Hybrid Ultra Soft #6
I also use this setup for slightly heavier applications:
Phleuger President spinning on a Team Allstar 6'6 L
Yozuri HUS #6
Both are VERY smoooooootthhh. And I highly recommend the Yozuri line. Very abrasion resistant and strong as all get out. I've pulled in 10lb stripers all day long in strong currents and not broke the line once. Also, if you hang up, you are likely to pull the boat to it or log out of the water with it
