I don't know if I regret anything I've bought. I think if I did I would stop doing it.
Really don't use that much though. Honestly, if I have some 3/0 hooks, 1/4oz tungsten, and some menace grubs I'm pretty good 90% of the time on lakes. And in my shallow river it's 90% Berkley Choppo (shallow water + rock = smallie nirvana).
