The Puma was an entirely forgettable disc, so much so that I forget all about it.
When it was released it was called a driver. The Stingray and Cobra were also called drivers at that time, so take it for what it is worth. The nose was way too blunt to pass for a driver by today's definitions.
Really, from what I recall it looked a lot like the Panther. The wing looked similar to the Panther wing except that it had a very small bead. The top was a lot flatter due to the Thumtrac®. The result was a more stable Panther-type disc, pretty fast for a midrange and easy to turn. All in all not a bad disc but nothing special.
At the time, Innova was looking at the end of their patent on beveled-edge discs. They suddenly started rolling out Thumtrac® discs, and I thought it was becasue the Thumtrac® patent was going to be good for several more years. If they could make it popular and license it to other manufacturers, it would help offset what they were going to lose when the golf disc patent expired. That was just my guess. At any rate, the Rhyno, Puma and Wolf all rolled out in short order. That's as far as it went, though. Other than the retooled Birdie (which really just replaced the Piranha) there were no more Thumtrac® discs until the Pig came out last year. So, I guess it never really caught on like they had hoped.
