I prefer winged launches; something like the Orion or Titov launchers from World of 2001 would be pretty cool. The launch vehicle would have rocket boosters, and can put itself into sub-orbit (but very close to full orbit), and then Cygnus could detach and do the rest. The other vehicle re-enters the atmosphere and bingo. Reusable all the way! I suppose you could do this with the TX, but a custom booster seems much more interesting (and would take some work to model and configure and the rest...).
