In the time it takes to get a hold of Pete to have him send you a Boomerang, you can run to your local hardware store and pick up several S-hooks to try an alternative procedure. I wish I had recorded the size, but
this image should put you in the ballpark. You "might" spend $2 bucks if you buy 3 - 4. Once you have the correct size you're off and running.
Nothing wrong with the 50/50 method, but I prefer the S-hook to both the Boomerang and the 50/50. Give it a try; if it you like it, great. If not, it only cost you a few bucks at the most.
Here's the link to the video demonstrating how it's used.
