I've had a preference, but I don't know why, for the round bend style of trebles and have been satisfied with a number of brands, including VMC, Gamakatsu and Lazer Sharp. Not that it's any of my business, but why not check the hooks first before replacing them? Many crankbaits come with lousy hooks, but others come with pretty decent hooks which will do the job just fine with a couple of strokes with a hook file.
