The only thing I can think off is with the traditional buzzbait (top lure) the frog will sit a bit lower in the water than the inline. This may get a few more strikes from fish hesitant to break the surface. Some people say inline buzzbaits get on plane faster but I haven't notice a difference with a frog on it. In pike and musky country, the inline is easier to fish with a leader. You will have to put surgical tubing over the R bend on a traditional bait or the leader snap could slide up or down the arm.
I don't like to change blades on a traditional buzzbait. Before I put the rivet on, I scuff the top of the rivet with sandpaper. After I put the rivet on, I crush the tube part of the rivet with needle nose pliers so the rivet won't spin with blade. The blade spinning on the roughed up rivet top makes a good squeal.
