I'm looking for some type of lure like maybe a lipless crank or something small enough for perch but will also catch bass. I was thinking about the Xcalibur xr25 bug it might be too big for perch. I was also liking at the tetra works bivi. What do you guys think I should get

Small in-line spinners will catch just about anything that swims.

Perch and bass both take a wide variety of lures and anyone who fishes perch waters has probably caught a number of them while fishing for bass. I'd try a happy medium, such as a 1/4 oz. lipless crankbait, not too small for a bass and not too large for a perch. I'd take the same approach with other lure types.
