O' Ring size for wacky worm?

What is the best size O' Ring to use for Yum Dinger and such?

There is a kit you can purchase with "O" rings to help put them on senkos. Not very expensive and worth the money as it will only take a few seconds to install them. It can be purchased from Bass Pro, probably Dicks sporting goods and I think Backwaters in Lexington carries it.
