On the telly last night I watched a show on fly fishing for bluefish and the guide had a 9',9wt. rod setup with a sinking shooting head and he said that it was the hot setup for beach fishing or for windy conditions. What he didn't say was what size shootin head ,I.E. what size for what weight fly line and how to finish up yhe whole rig. Would I be correct in assuming that the shooting head attaches to you flyline, and at the other end you would use a suitable leader of mono then attach your wire leader to that ,then attach your fly to that? Are shooting heads sized the same as the flyline? Would this whole setup change your casting timing and method? Thanks in advance from a semi-newbie fly chucker.
