I am wondering what technique people prefer to use in throw me, personally I go for a horizontal throw aiming for a layer of clouds and "ride" them using the space bar until that runs out. At which point its just down to luck!
I like to start by flinging it at around 850-1000 mph horizontally on the bottom of the screen (maybe mid-way up) Trying to not get any height. Usually you will hit a booster and get slung at about a 45 degree angle, at about 1300 mph, often hitting the booster cloud sending you in the same direction at about 900-1000 mph.
I usually save my boost for the last seconds. If the person starts to slow down, I give him with a little nudge from the boost, hopefully propelling him far enough to a crane to start the process over again. But as always, this strategy takes luck.
