Nate has probably played this course. Maybe he could fill us in.
I'd go with an Orbital to start.
I don't suffer from internet distance syndrome, therefore, a Sidewinder / Thunderbird are the fastest discs in my bag. I could post what I think McBeth would throw, but I'll just stick with what's in my bag. FWIW, a Sidewinder / Wizard combo easily covers 450'-500' on a flat hole like that.
