Though I have known of Legacy discs for a while now, I have only recently stepped out of the Innova "box" and been willing to give other disc manufacturers a try. I do not own a Legacy disc yet, but thanks to Lion I will soon enough (Cannon). I can relate some recent experience that has generated my interest though.
What I like best: Played a round of dg with a group one week ago. A Grandmasters age gentleman had an Icon Cannon and was getting driving distances from it that I had never seen him get before with other drivers. I was impressed. Also, my first Legacy driver will arrive this week from Lion. I feel like I got exactly the weight, color I wanted and a great price to boot.
What I like least: Also played a round of dg a few days ago with a different group. One player had two pinkish/salmon color Icon Cannons. He talked about how OS both discs were, very OS. That surprised me. I thought the Cannon would be a less OS than the Rampage, but he stated they were not. We spent 10 minutes throwing both his Cannons, and they were very OS indeed. So the flight was not as I imagined.
I've read that different colors of the Icon Cannon are more or less OS. Blues and whites less OS, purple, greens more OS.
Can't wait to get mine and figure it out for myself.
