Both this and this question provide good advice for various types of rocket-jumping, and I have followed these jumping techniques to the best of my ability, but there is one technique that continues to elude me as a solider.
Rapid forward momentum.
My rocket jumps carry a little forward momentum, but not nearly the map-crossing, spawn-killing, game-ruining techniques of legendary rocket jumpers.
What type of rocket-jumping can provide this tremendous forward momentum? Specifically, I know that 'skipping' provides map-clearing capabilities, but what about the initial momentum-creating jump? What are the ideal conditions for such a jump?
