The 'answer' is have Steve Gotshall build you a head system.
Shooting line is separate and looped as are the heads. You want to change the presentation/sink tip/poly leader/etc., all you do is change to the appropriate 'head.' Mark up some zip lock bags with what the head is (and for?) for storage.
No 'credit' to me for the zip lock bag bit that came from J D Jones here on the board.
