I have attached 1/16 oz bullet weignt around 1 feet above the hook. Is it too much weight for small crappie minnow?

From my experience, with too much weight small minnow gets tired and die fast.

I have been using 1/32 oz bullet weight, with this weight crappie don't get tired, but don't do a good job holding the minnow down at the bottom.

Thanks
