Well... on that map in particular, I am (not to toot my own horn) one of the top five players in the world. Yes, we have had tournaments for <b>just that map</b> and I've traditionally done very well on it. It comes from having played it for an average of, I'd guess, three hours a day for the past three and a half years. I'm not as good on other maps as far as movement and map knowledge, but my aim is about the same all around.
That rocket shot is one of the hardest to hit in the game, in my opinion. It's one of my favorite shots, except for the time I put 3 grenades into a guy in the air on pro-q3dm6 (the middle bouncepad - one as he came up, one as he was in the air above and in front of me, and the final killing shot as he fell to the ground below. I have the demo, I'll make a movie of it some time).
If you want, we can play on a server that's very close to you. I am stupidly ping dependant (I had really fast DSL and usually would ping sub-30 to most east-coast servers, meaning that I had big trouble playing with a ping greater than, oh, say, 40), so it would probably be more fair, what with both of our shitty pings.
