The defense primarily

The router Gravity destroyer is a top defense. i.e. that its tip is very broad and flat. It resists the assaults tremendously and continues to turn long.
Its main feature is its ability to turn right or left. The majority of top turns right except "L.Drago" which revolves exclusively left.
The router comes with a launcher on the left (which is rare), you so another router for a pitcher to right.
It is the top favorite of my son.
