Full sink or Intermediate fly line
I'm looking for some thoughts or suggestions on whether to use a sink tip, intermediate or full sinking fly line. I am fishing for canal tarpon in about 8 feet of water and need to get the fly down quickly and keep it down. I am throwing to rolling fish and areas where they consistently roll. I have thrown some heavy flies ( no fun to cast) to get the fly down but I need to keep it down lower in the column for longer. I have been fly fishing for 25 years and never needed or used anything but floating so this is new territory for me. Any help is greatly appreciated.
