Should i keep on using my lucky bronze rod or go for another rod?

As i love fishing in this game, what rod should i switch to? or i should just keep.

Luring bronze rod for more fish and magnetic collector rod if you want to sunken gear hunt

I want to earn more crowns, as i want to at least afford something from the sunken tier.

Ah then lucky bronze is pretty good. Good pure and higher chance of rare fish meaning profits.
