Bullet/worm Weights

Best advice I can give you for picking a weight. Use the lightest possible weight you can get away with while still maintaining bottom contact. If you choose to use tungsten weights you can almost get away with slightly lighter than normal because it transmits vibrations better letting you feel the bottom.

 If you're pitching & flippin' you can pick it based on rate of fall and/or enough to get it though whatever cover is present.
