I like both choices on their own but like the smaller metal and glass pendants with the crate chandelier. They're very pretty and elegant but still rustic enough to work with the crate lighting.

Plus, since you already have the wood element going on I think the metal pendants would be a nice complement instead of more of the same. Should be very nice!

We have a 4 x 9 island and did not want the possible "clutter" of the three pendants so we opted for two large pendant(19") and then put a can light in the center over the sink. We definitely needed that extra light in the middle.
