You don't know the ins and outs. You aren't particularly much of a fisherman/woman, and you haven't caught more than one bass in your entire life--unless you're lucky.
Decent at Bass Fishing
You're not the worst at bass fishing, so that's better than nothing, right? You've done it before. You certainly have caught about two or three of them, but you're not an avid bass fisherman/woman.
Good at Bass Fishing
You are a good bass fisherman/woman! You certainly know how to handle yourself out there on the water. You're good. You know most of the things you need to know, but you're not an expert either.
An Expert at Bass Fishing
You are an expert at bass fishing! You actually know what you're talking about. You know what you're doing, and you know how to make things happen. Every time you go fishing, you catch yourself a bass or two.
