JK Pro Aviar-x vs. Champ Aviar P&A. differences?

[fireball42]

So i currently have a champ aviar P&A that i put and occasionally approach with. it was the first disc i bought and i had no idea what i was looking for. I played a few times recently though and the champ plastic was slippery frequently. I am looking to purchase a JK aviar because i really like the feel and grip of it as well as its softness seems just right.

I am just wondering if there are any other differences between the two discs other than plastic type and stiffness?

I think the only difference might be in the bead. I've only thrown the JK Aviar-X, several years ago and it had a bead, not quite as large as a Wizard, but definitely there.

so other than how it feels in my hand, which i already like, how does it affect the flight pattern? more or less wind resistant? etc?
