I have a few sets of banjo minnows. I like them for bass, but they have the typical disadvantage of any plastic bait, damage - wear and tear. If a pike gets a hold of it, its pretty much done for. The hook system works fine for bass, just let them run with it before you set the hook, but sometimes the pike never take the whole thing down. Especially if you use the larger minnows and a smallish 18-20in pike grabs it in the middle, you'll never get a good hookset on him.
For bass, I didn't use any weight and let the 'buoyancy' work its majic. You have to be patient because it sinks slow, but if you get a good cast, it stays in the hit zone longer. I never tried the jig head system.
