My 167 GL Fury acts like a fresh Opto River for me. Probably a little longer but I'll test it against a 164 Opto River for reliable turnover shots. I'm curious what it will beat into...hoping for a beat River that isn't absurdly flippy.
This is a nice disc for turnovers because it doesn't turn out of the box. It starts for me about mid-flight and fades out at the end. I think Rivers come out a little turnier, but that could just be me.
I haven't thrown my Opto 167 on the course but it was surprisingly more understable during field tests. Usually Opto goes the other way.
