The Innova Shark DX was my first disc. I still have it and it works great for long approaches and the occasional putt. Plus, can throw a mean anhyzer with it (although, sometimes randomly). It has lasted me almost the year and has taken the most punishment and will not give up.
My first disc I found 99%buried in some muck. Turned out to be a first run XS. I was sooo crazy about that disc. It wasn't in great condition when I found it, obviously, but I loved it. It ended up on top of a barn and stayed there for years. I wanted to get it down, but the storm did that for me and the dog ate it. That was a sad sad day.
