It's not bad at all. But fouling has a lot to do with casting style so YMMV.
I thought about making a "hairpin" out of light wire that would hold the hook up against the spoon via the tail hole.
Then it would release with headshake torque.

Fouling was not much of an issue so I didn't pursue it.

When he's hooked up to it, it's a good thing. Definitely harder for him to shake it.
Test it....if you like it do an STS How To on it.
