I just bought some snap swivels (safety pin style) today in the fishing section at Walmart. The Estes Omloid nose cone is large, and probably as heavy as any nose cone, since it contains an egg.

A "3 snap swivel is big enough to attach the Estes Omloid nose cone.


Here's a link to the snap swivel from the kite store:

(looks identical to fishing tackle snap swivels)

If anyone has information on better quality, more reliable snap swivels please reply!
