i use 30 lb flouro in the chesapeake . with small blues isnt a problem. on the larger boys i would use wire or go with the long shank kooks tied at the bend. i am not a fan of circle hooks but they are good and do their job.
For big blues only, I cheat an put on a 6 inch wire leader. The ones you buy in pack. They are thin and have a clip on the end and a swivel on the other. Work well and cast fairly well. Found even stripers will hit the flies on the wire too. Only use them when I have lost a number of flies and know there are big gator blues around. Either way the flies get chewed to death along with the wire.
