On the tripod and in the hand.Are you sure the bass stocks weren't just better? It's one of those things that probably need a multi-varied analysis to give a clear indication. I have been on the pier with 3 of us on j's and one on circles, there was one person who had a tiny catch volume vs the other 3, wasn't connecting (talking schoolies mostly). I think circles are much kinder and great for some species but, I trust them on bass about as much as I trust Joe Biden to remember his last sentence.
Are you fishing two rods in a tripod? or one rod in hand when bassing? As that may be where the secret lies.
Bottom j top circle.
Don't strike just wind.
99% hooked in the scissors on the circle.
