They are subsurface. They will not stay on top. They will hang around just under the surface with a slow retrieve. They are belly weighted, not heavily and no tail weight. The line tie is on center and right below where the two cuts meet 30 degrees on the lower 60 degrees on the upper. I also have a small shallow scoop on the face that is only below the line tie. Don't know if it helps or not as I have not done these without it. I was real excited when I swam the first one. I liked it so much I didn't want to mess with it by trying to tailweight it. here is a pic of the face.
