I like these in soft plastic best. I use them to get out of trouble and easy turnovers, flip up, and rollers. The 9 speed allows big distance as well as control. This plastic is more stable than the softest D-pro, which I was actually looking for when I found this one. But in a season or two it will beat in about the same, I expect.
In this soft plastic these are like some variant of a speed-9 Leopard type disc, if you want a reference. And for reference, I bought a Z heat a while back that is much more stable, and needs 9 speed throws to do its thing. This softer plastic allows more touch shot, but at full crank it will turn all the way over.
I really like Discraft's 9-speed lineup.
