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.
Let me make sure everyone knows my age. My first disc frisbee was a whamo 165 gram that I could throw 300 ft on occasion. I carried a whamo 141 gram and a 199 gram as a putter. Be aware this was in the mid 70"s!!
