MM,
If you are thinking about getting the clip bender, it makes sense to include a dozen or more of the wire pieces Jim offers. It all becomes 'turnkey.' His wires, as he mentions, are the ones Derek designed the clip bender around, and have the strength you'll need.
A plus: I don't think anyone mentioned it in this thread, but the nut and bolt arrangement allows you to make clips in different lengths, so you can trim "neutral" by fitting a needed length at the needed "line" on your handle.
