He says "... flies similar to my ExCals, a little faster, I can get a little more distance out of it, more replaceable. It made the bag recently and I've been really happy with it..."
He carries it. It's his second favorite distance driver behind hard-to-find proto ExCals. He didn't say "I carry this P.O.S. because it sucks and I like to throw it into piles of poop."
It's an underrated disc. The good ones are really good. And they are definitely more HSS than Terns. And less so than Destroyers and ExCals.
I like Glow Terns, but for slightly more HSS, I'll throw a good overstable MF Teedevil. I'll let rip on AJ Destroyers too, but the Teedevil is the straightest of the bunch for my arm (all three around 400').
