I would agree with Jason. One key part of understanding this trick for me was seeing it as a series of rapid half axels. You may want to start by mastering this move first.
A half axel cascade is also very related...in the sense that it is of course alternating L and R halfs. The comete is just R, R, R, R, etc. or L, L, L, L, etc...depending on rotation direction.
Just one final bit: The input which brings the kite back from the 'flare' or the 'fade' position is a very light one...NOT a pop like the main input to initiate the 'flare' or 'fade'. It is more like a lifting tug, like the second input in the half axel cascade. (See Kareloh's response.)
Yes, no disrespect here, but you are trying a very hard trick a bit out of order from the traditional trajectory. On the other hand, who says you need to learn in any particular order? Not me!
(It took me about 3 weekends of fooling around with before it really started to click, and I could fly loads of other tricks fairly consistently before I dared.)
