Why do most aerobatic aircraft have conventional landing gear? I was browsing images of aerobatic aircraft on Google and noticed that the vast majority of them have conventional "tail-dragger" landing gear.

Is there any practical reason why this is the case, or rather an aesthetic preference?
The tailwheel is much lighter and smaller than a nose wheel. That means reducing airplane overall weight and drag (because the landing gear is usually fixed). And it's probably cheaper, too.
