Brand X Golf disc was my first "golf" disc, while the first beveled disc I had was a Patent Pending Aero with a Brown Deer Park hot stamp. Before I used these, I had been using a 165g and 141g World Class Frisbee.
My friends gave me my first disc.....a dx teerex.... Thankfully that was the first disc I ever lost.
First discs I bought were a 167g champion roc, 167g dx shark, and a dx rhyno. Don't carry the rhyno anymore, but the roc and shark are still in my bag, 30 some discs later.
