I always launch east for everything (except polar airplane sightseeing) but whether i hit the mun\'s leading edge or trailing edge is quite random for me. I wait until munrise for the TMI but its not that precise. But the Intrepid II is good enough to do either one. I completed kerbin orbit, TMI, munar parking orbit, and the deorbit burn all with the soteria booster. Unfortunately me being dumb caused the fully fueled lander to hit the surface at 200 m/s
