They're painted spoons so neither would be preferred to use on the rocks..
But from the beach what are you targetting, for the S cape species there are much more effective spoons. I use what is tried and tested for decades..Problem is lead is 1/20th of the price of what you want your spoons to be made from, and the legends that still make them do it more as a favour and a hobby these days. All the time and effort spent in making molds, silicon, procuring white metal, and making all the wire throughs..and then they are making R10- R20 a spoon so they can still wholesale. They aren't making a living off the work, when they stop I will have to start making my own..
I do use the couta casting spoon as a casting weight for my sabiki trace and the mackerel do absolutely love it. The magic missile looks like it will cast a mile. But I'd still fish my abu in the same situation.
