#4s over dekes is all you need. Geese over decoys #2s or BBs if the shots are longer. Kent Faststeel is great stuff. Its all I shot for years. Most of the new steel out there is way too fast!!! I think anything over 1400 FPS is just marketing hype. For woodies early season all I use Kent Fast Teal #5s. That kills small ducks nicely.
