Been a big fan of this game for several years. I have only played the "career" path, and never seem to get very far. Then a new update is introduced, and I start to play again. I'm simply loving the 1.0.4 version. To be honest I was getting a little ticked at first with how much more difficult getting a craft into orbit was, but after reading a few posts, watching a YouTube vid, I quickly realized that VS. 1.0 introduced/implemented the new aerodynamics/drag/thermo physics,(which is cool as heck!). However, I'm simply wondering why the LV-N has become so, well, useless as far as I can tell? I'm at the point in my "career" that my next step is to get to Duna, but the LV-N is no longer the go-to engine for inter-planetary jumps, what is going to be the best engine to get me there?
