An "edit" of the above (Bob, where the heck did you hide the "edit button?")

If you're going to use a DT line for a 'launcher line' CUT off the forward taper back to the point of 'level line.' Put on a loop and you're good to go. If you use one of the 120 DT spey lines you can actually cut it in half and have two tip systems.
