Somebody telling someone else how to play a single player sandbox game isn't getting the idea. Play the game however you like because really, why should someone else tell you? I've never used any of them, but launches get really boring after a while. It's fun and all to design a new lifter or a new ship, but getting into orbit just becomes tedious and repeating. Most of the time I simply check the weight of my payloads, check if I have a lifter capable of taking that weight to orbit and just use HyperEdit to get it up.
