The Axiom Fission Defy is an overstable distance driver, Axiom's more torque resistant answer to the Photon, built in the airy Fission plastic that shaves weight without giving up any of that high speed stability.

Flight Numbers: 11 / 5 / -1 / 3

Fission uses Axiom's microbubble technology, so this Defy feels noticeably lighter in the hand than a Neutron or Proton version at the same weight. That lighter core does not cost it durability. It takes a beating on the fairway and keeps flying true, and the trade off is a slightly less premium, more matte grip than Proton, though it still holds fine in dry hands.

Thrown flat and hard, the Defy holds its line for a long way before it dumps into a hard fade, closer to a bullet that drops than a disc that S curves down. It carries more high speed stability than an 11 speed label suggests, so a big arm gets a long straight flight instead of a giant hyzer flip, and a smaller arm gets a shorter, more overstable flight than the numbers promise on paper. That makes it a bomber into a headwind and a control disc for anyone who needs the fade to shut a hole down. Backhand and forehand load it the same way, and it rewards a flat release over a hyzer.

Want a flatter, longer flight before the fade sets in? The Neutron Defy carries extra weight and a slower beat in. Looking for a special run of the same mold? The Prism Proton Soft Defy (Champions Cup) is worth a look. Browse the rest of our overstable distance drivers.
