Innova Caiman Flight Numbers: 5.5, 2, 0, 4 Drawing inspiration from the Gator, the Caiman muscles its way into Innova’s mid-range lineup with a strong fade and minimal glide—the Caiman thrives in a headwind. The microbead gives the rim a smooth feel, perfect for power forehand throws. What's that last number next to the disc variant? That is a dome rating! 1- puddle topped 2 - board flat 3 - normal feeling disc 4 - slight dome 5 - pop top
