Right about when I really started playing regularly, the Roc was switched to the Ontario mold. ORocs and Sharks were really close, but the ORoc had better glide and I could throw it farther so throwing a Shark made no sense.Fwiw, I hate domey rocs too. I was throwing flat tops prior to the roc3. No issue with beads though. IMO bad flashing on candy plastic is way worse on your fingers than a bead.
As far as the shark, it's been so long that I don't really remember why I disliked it so much. I know it never felt right in my hand. Really don't recall how it flew for me.
BTW I think Dave D. hates Rocs; did you watch that video? The disgust on his face when he said "significant DUMP...at the end of it" gives it away.
