A looooong time ago I had a great fight with a guy named Mfreak and one of his friends. They were both in la5's and I was in a D pony. We ran into each other basically at co-alt (around 10k). The fight quickly ended up on the deck where we went at it for at least 5 minutes until his wingy clipped a tree then it was down to freak and I. We went at it HARD for a good 10 minutes more until his la5 ran out of fuel.
I also ran across a guy thats name started with a 'N' (all i can remember) We were both in D ponies and we went at it for a long, long time! All the while on the edge of a stall. Best pony v pony fight i've ever had although it was sad because when we started there was nobody even in our sector but by the time we finished some "friendly" tard in a jug came out of nowhere and dove in and picked him. I tried sending him a message but he was gone and I never seen him in the MA again.
Also any fight with Creton or batfink...Always good ones if you can stay alive long enough to enjoy them
