I've started a Roc Collection, and I have a few favorites.
Primary thrower is my beat dx roc, that has been "dead straight" for months now.
Fresher Flat Top DX for when I appreciate a bit less glide and the late fade.
12x KC Rainbow Stamped, this one is less domey than most of my back up dx rocs, but still domier than my flats. I have two more KC's that look similiar, and i could swear my 11x is slightly domier.
I've got 8 bazillion backups and discs waiting to be rotated, but looks like I'll get a whole nother summer without having to rotate my 3 out. I have a quite a few woods ones that didnt even get pulled this year. Star Ontario, Star Rancho, Star SM. I think i'd rather just replace a KC over the next year than use the Premium plastics, they don't feel like they fly the same.
