At level 18 you most certainly want Cane of Harmony in your mainhand and Cane of the Tranquil in offhand. Damage bonuses are minimal until higher levels, so you should mostly be concerned about the ratio of the weapons you're using. Trance stick won't be worth using in main hand until much later, and by then you will probably have better. Totally overrated weapon unless you need the proc, in my opinion.
Here's a chart that spells things out for you based on weapon setup and level (credit to Yaolin):
