Anyone got any most efficient tips on what way to get to say Jool or other planets from low orbit Kerbin? In other words, there are many ways to get there, but one is usually most efficient for fuel or time, but not usually both. For instance, I plotted a course to leave low orbit from the Mun to Jool with only about 1850 dv. But it requires first getting to the moon. Which seems to be a waste. There are other paths that can be much more efficient. Straight out from Kerbin but would need a large boost in dv on the last orbit before escape. What is generally the best way? Using the Mun for a sling shot doesn't appear to be the best way. Sure it saves a bit on Kerbin escape, but then you have to add a ton of dv (usually about 2500 or so) after. Going straight from low Kerbin orbit seems to work better but requires a quick and fast burn to stay on course. Just want to know your way, why it's best. Thanks.
