What matters most
The leaf-spring design is the Thunder 2's main draw, moving the springs to the frame base instead of across the mat edge; it is a 145-inch round at about $879. The HERO uses coils in sizes from 10 to 15ft at $749 to $999, so it is easier to fit to a specific yard and starts cheaper. The HERO is rated to 350 lb against 330 lb on the Thunder 2, and carries 5 years on its springs versus 1 year on the Thunder 2's leaf springs. So the trade is the safer-feeling edge against more sizes and longer spring cover.
