I say stick with the kilo, getting a fancy track frame is more for the simple idea that once one outgrows riding the starter bike, buying some $1000 NJS Stamped super rare Keirin racer's old bike is in order. It isn't, some of the most dedicated fixed gear riders I know has 3Renshos built up yet still continues to ride a bikeisland frame. If you want one for cool points I'm not gonna advise against it as it's your money, if you want one cause you think it will improve your riding speed/comfort/enjoyment it's not gonna give you that unless all you care about is the name on the downtube.
