Discraft ratings says the meteor is a -.5(thats a negative .5), the buzzz SS is a 0, and the Buzzz is a .5.
Keep in mind, the kind of plastic used to make the disc can change stability. Used, but not overused, Z and Xelite plastic are what I have in my head to be the norm when it comes to Buzzz flight( thats my Base for a .5 rated disc). EsP tends to be a little more understable and the EsP FLX even more. Now on the other side of the Buzz spectrum, the TI is pretty overstable.
I think that the meteor sounds good for you. but
Next time your out praticing try holding onto that Esp buzzz for a bit longer, and hold a little tighter. I bet youll get that thing to anhyzer for more than 50 feet before flattening..Good luck
