60% is not under powering the Tern, thats what I am trying to say. It would be under powering a disc like a PD 2 or even a Star Destroyer. Thats why I called the Tern a finesse driver, you can finesse it at the right angle given proper conditions and it will glide a long way with much less effort than a disc that is much more stable.
Actually, yes it is. And the speed 9 PD takes WAY less power than a speed 12 driver like the Tern. I think you've been away from the game too long. Also, most disc golfers would NOT call a speed 12 driver a "finesse driver".
