well here is some actual advice on the Coupe as opposed to the previous "its a groove, it sucks" response.
The Pro Coupe has a big bead on it. It is basically a shallow JK Pro Aviar. Imagine taking an XD and combining it with a Big Bead Aviar. That is the coupe. The plastic is decent, but kind of weird. The outside wing is stiff pro, and it gets softer the more you move towards the center/nipple of the disc.
I actually found that it is a useful approach disc. The plastic holds up basically the same as JK Aviar, takes slight gouges but nothing bad. It holds straight flat lines and can flip up flat for slow turnovers. Really it is a good disc if you use it for what it is intended for, approaches to the basket or longer putts. I didn't like enough to use it over my Omegas, but if I magically had 10 in my backstock I would probably start using it as a turnover approach putter
