Hi Superman
Have you tried practicing without any Poi atall? This helped me get used to the movements (and saved a hell of a lot of pain as I whacked myself constantly). I had the same problem trying to get my left hand as flexi as my right, and I recently started practicing again and it took me a whole afternoon to get the low wave down, all 'cause my left hand wasn't so good at co-ordination.
As Jeff said, practice solely with your left hand, when it's as good as your right, put it togther.
When doing the alternate butterfly, when swinging your left hand over your shoulder turn your head to the right and to the left when you swing your right hand.When swinging, make sure to rotate your hand well and relax your body, as the key to pulling off this move is fluidity.
Persevere - You'll be doing alternate butterfly's and waves in no time.
Gambare!!
