Hey I was just referring to "Betts style" spinners in the same sense that people call vacuums, hoovers.
The actual Betts branded ones would be much too small - but others around have made bigger ones. The last ones I bought were from a BassPro shop in the USA.
Just showing the idea of the detachable arm that has a spinner blade on one end and a clip for your lure on the other.
Umbrella rigs certainly look unwieldy - and I definitely don't think I'd ever load them up with hooks on all the prongs - but nothing else I've seen looks/moves like a school of bait like they do.
