Yeah that's typically the choice for me. By not spending the 500 I virtually guarantee with my typical route that I can go to Willy's on Day 3 and buy a Fiberglass Rod, 50-60 bait, and a trout soup. I'll eat the soup when I've got enough missing energy while fishing for catfish, both for the energy replenishment and the boost to fishing. Maybe not optimal but that's typically where that money goes for me.I guess the obvious answer is a Fiberglass Rod. Get to bed by 2 on Spring 1 with whatever money and shipping you can. And on Spring 2 spend it all on a Fiberglass Rod assuming you have the ability with the Training Rod to be money positive and get to level 2 before 5 p.m.
Edit: Oh sorry misread, you can't buy the Fiberglass Rod on Spring 2, even if you get the money for it by close and are fishing 2 by close. It won't show in his inventory until Spring 3 at the earliest, unfortunately. My answer still applies but sadly at 9am on day 3. Sorry I don't have better news there!
