Haven't beaten 108.891M yet myself, and the "trick" is to *NOT* loop-the-loop at all (let alone twice, great way to ruin an otherwise good throw...) Sotiris, your launching technique definitely helps with the longer throws. Just to help the rest of us, are you leaving the plane at the very top of the screen, or slightly down a bit, or what? And in terms of the "launch", where do you bring the mouse pointer back in.
Personally, I've been putting the plane about halfway between the dado rail and the ceiling, and I launch with the pointer a little above the skirting (otherwise it hits the floor if you're lower on the launch point)
