Maybe in another month or so it will be good for you night and day. Congrats on the ones you did catch.
When you were night stalking, were you fishing directly below the light, or in the shadows around it? I dont do any night stalking but from what i read, they like to hang out just in the darkness around the light. Hopefully that was your problem and it is a simple fix for you. Other than that I dont think i can do you any good.
