Ken did ask about "Hello Kitty" clips, not the ones most of us use. Otherwise, I agree 100%, call up Jim Lee and get the bending tool and wire for making Derek Moran line clips.
I do have a few words of caution about these clips. DO NOT go nuts and make dozens in all lengths up to +1" over stock clip length. If you want to make some "stock" clip length clips, help yourself, but almost anybody can make up a set of lines that is within 1/4" of eachother...and probably more like 1/16".
I like to use three standard Sullivan clips, keep one clip on one leadout, and both clips on the handle, including the oddball homemade clip. This establishes which line goes to the oddball clip. I hook the lines to the plane first and roll them out and hook up the handle by looking at the elevator and pulling each line. Between rounds, especially on a grass pit area, I remove the handle and roll the lines up to the plane and put the handle on top of the spool, so as to keep my lines from being abused by others who have no idea how to get in/out of the pits without stepping on or snagging somebody's lines.
