You're the one who came in here and started dropping unsolicited internet expert advice. Sorry, but I'm not the troll here.
If lighter discs fly exactly like their heavier counterparts in terms of stability and I'm simply having a nose angle issue as you suggest, then that same issue would affect both the heavier discs and lighter discs equally, and thus I would be flipping everything the same way. You contradicted your own logic without even realizing it.
Actually I didn't. It's completely conceivable that a lighter disc could be more nose-angle sensitive. And two people subsequently agreed with me based on their experience. It's not about being an expert. Just about posting my experience. Which is kind of the whole point of this forum.
