The Mortar is one of Hyzer Bomb's first releases, and is a nice stable flyer for power throwers. Other players will find it to be pretty overstable, making it great for those tricky headwind shots. Reliable and predictable in the toughest conditions.
The Frontline-X is a gummier version of the regular Frontline plastic.
