Yes, I do.
Go right north of Sunyshore City and surf around, you will find Tentacool's and Tentacruel's. Tentacool gives off 1 Sp.Def EP and Tentacruel gives off 2 Sp.Def EP's, this is where I Ev Train. Theres the occasional Wingull and Pelipper (don't battle them), but the Tenti's are way more common.
