Do you have OAT issues? Some OAT in throw might turn disc over than expected.
OK, I might check the PLH out to learn more about Disc shapes. I will admit when I got the Amp, I thought that the rim felt pretty heavy and thick to be understable. But when I got the Shock, I though that it felt kind of light and slim to overstable. But I don't think I threw them any differently.
I haven't filmed myself driving, or gone to classes to get feedback on my form. So I can't really say if I suffer from Off Axis Torque. I'm sure at some level I have that problem, or I would be getting better scores. Could certainly be that that is why these discs don't behave how I would expect. But at least in the case of the Amp, I think the particular disc I got in the early white batch was not quite right. Because I should be able to turn that over. I could turn over a 175 g Rampage better than that one :P
