I'd recommend sticking to what you are doing with just one pop for now. To begin with additional pops will just complicate things.
My tip for you, which most seem to overlook, is rather than thinking about what your hands are doing.. think about what your feet are doing.
In no wind you will be walking backwards, in light wind stood still, in standard wind walking forward slowly and in strong wind walking forward briskly.
Correct ground movement will significantly improve the quality of this trick without having to change the hand movements you've got working already.
Once mastered with the one pop.. I would then add an additional pop which, for me, is used to improve the success rate of each individual axel.
Thanks for the tip, Dave. Remembering my footwork made my yo-yo hit rate improve dramaticly.
