The Innova Pig in Stiff Pro plastic is a firmer, less flexible take on Innova's most overstable approach disc. Pig already refuses to turn over; Stiff Pro makes sure it stays that way even when you rip it as hard as you can.

Flight Numbers: 4 / 1 / 0 / 3

Stiff Pro plastic holds its shape under pressure better than the softer R-Pro blend, trading a small amount of grip for a rim that will not flex or fold on a hard forehand. That stiffness is exactly what lets this Pig take full power throws without turning over, and it holds its strong, dependable fade for a very long time.

Thrown flat and hard into a headwind, it flies straight and drops with a heavy fade right where you aimed it, without skipping or rolling away. The rim is thick enough to cut through crosswinds better than a standard putter, and low glide means it goes about as far as you throw it and no further, which is a feature, not a limitation, on tight approach shots.

Good for players who want a driving putter that can be thrown at full power without fear of it flipping over, and a reliable choice on gusty days. Less useful if you want a soft, grippy putting feel.

Want more grip in exchange for a little less stiffness? The R-Pro Pig is the softer standard. Prefer a glow version for night rounds? Try the Color Glow Pro Pig. Browse our overstable putters.
