To all people that create their own spinnerbaits.

What Swivels do you use and why?

Do you notice any major difference (smooth spinning action) between the two?

The reason I ask is because a crane swivel with split rings is much cheaper than the ball bearing swivel.

For my own spinnerbaits I use a Bass Pro Shops Pro Qualifier swivel because both ends spin and I get more thump and my blades turn easy at slow speeds. The major difference between a crane swivel and a ball bearing is that a crane is cheaper and the blade don't spin as freely as one on a ball bearing. Most ball bearing swivels have one end that don't spin and the other ends spins real easy. This makes a blade easy to start and the vibration is uninterrupted. A crane rusts easy and can hang up sometimes. If your building to sell a ball bearing spinnerbait would sell better than a crane and you will get more return business. Look up Stamina on a web search because they sell some less expensive ball bearing swivels.

Thanks for the excellent answer!!!!!!!

Ball bearings are the way to go.  I use the spinnerbait swivels from Stamina and have been very pleased with them.  Here is the link to Stamina:
