I got to throw my Amps at the course today...It was a bit gusty, but nothing I'd switch out any of my normal discs for. I put them through quite a workout on a range of shots from approaches to tailwind distance drives. I threw them FH and BH as well.
First off, at least I'll understand from a firsthand perspective the variation in this mold (unlike the Volt) because the two I have are different discs stability wise. My stormtrooper flies a lot like ZJ's description...It likes to get some initial high speed turn, settle on it's line, and then fade late. It's a really straight hyzer flipper, and very controllable in it's action. For a high speed turning disc it flies decent in the wind and is pretty predictable all around. This disc likes to hold pretty straight in it's flight with just enough HSS on the hyzer flip to keep the shot from getting away.
My red Amp is one of the most understable discs out of the box I've ever thrown. I could keep it straight from a deep hyzer on 300ish shots, but farther than that and my shot always finished right. This disc has almost no LSS, almost coming to a stop in the air before falling left. Despite it's understability it was still useable to me, which was a bit surprising as I've never carried a fwy driver this understable. It's turn was slow and methodical and it is very insensitive to nose angle...I would just throw it with deep hyzer and watch it slowly work up and over and to the ground. It has good glide, but not as much as a RR. It really holds in the air on it's anny turn as well. I don't roll a whole lot, but this disc was easy for me to stand up and get good rollers out of right away. Overall it was responding similarly to the same release angles I use with my Mamba.
So I've got two new discs in my bag, both with their own merits and virtues. They go really well with my stable Volt as well. So now I'm really hoping that MVP completes this trilogy of drivers with a true "0" HSS disc that has a decent fade(faster Vector) before they move on to faster stuff.
