Really hard question to answer. I guess I'll go with something of recent years. Doing the Althanas doubles tournament (lornius challenge or something?)with Canen(Shin). When we lost it was a shame, but the co-op between Shin and Elite Optic(me)made for a good surprise, especially as we managed to knock out Christoph & Flames who were favourites to win the tournament at the time.
I always wanted to see another tournament, but I don't know if there are enough people anymore?
