It's so much easier with 24's that's it's kind of funny. For years I thought it was a worthwhile effort to try to make an18 work, and then they would kink on me. And then after years, I realized that if I left one end loose, and just took the other end in my hand and guided to the next connection, the bending would take care of itself.
So maybe it took me until year 30 of my 50 year career to figure that one out too. At least I was able to teach an old dog a new trick.
