Listen to what the zill players on your tapes sound like. If you can hear really good zilling, and if you start to think of what you do as music, that moves you to another level. It may not directly get you over the hump of playing and dancing, but it improves your skill and your comfort with the instrument. Likewise, the good zill player will have a better chance at dancing well with zills, if she understands them as musical instruments. Maybe you'll find arm movements or changes in poses starting to happen . . .
Nothing beats just plain getting up and zilling while dancing, prioritizing the zills.
Also, you will never get stuck in boring, repetitive patterns if you're sensitive to zill music . Muscial subtleties or quick save, zills are worth the work. This size seems to work well for most venues. Before you buy zills, you should check the sound. It should be clear, not too loud and it shouldn't tinkle too long.
