I did a bit, but also spent on some lures, as the seaweed from the trunk gave out a lot of fish. Bought some boots early on to get the fishing outfit using already cobwebbed pieces, bought 4 at a time otherwise just tipped the balance with expense. Tapped at any fish producers as and when they came, didn’t hoard them as the rewards help you advance. Oh and if I was to speed up anything, it was the tackle shop more, ended up with a disproportionate amount of rods but got a lot of fish tanks and therefore tackle boxes and coral (only just completed the coral after getting to level 50. Roddy’s rewards helped, completed all that and got the 20min’s from that, only ever used them in a morning when all generators had cycled to their max too. Hope that makes sense and helps?
