if it were just my 10-24 I'd skip the xumes but the 18-55 and 55-200 both use the same ring size and they're skinny enough the 4x6 lees make them into T shapes in the bag, so for them I went xume. I also use both of those lenses a lot more in non landscaping settings (people shots) where I don't want the ring on there (especially with how wide it is). But yeah, it all depends on what lenses you're doing this with and how you use them.
I went with a hoya HMC since it's not too expensive in this size (67mm). Here's a shot of the two size options you have:

I went with slightly larger which means you CAN'T use your hoods and everything is slightly more expensive, but I LOVE the slightly wider look (it's like a mini hood) -vs- the tapered look going smaller. The added step ring and xume both combine to make enough of a hood it's all I'll use anyway.
Also, get these:

xume is supposedly working on lens caps but until they do grab those and a spare filter ring for each lens, it's MUCH better than fujis caps, but the fujis won't work once you step the lens up/down anyway.
Thanks again Ben, Ill go the 67mm route and live without the hoods I think.
I need to stop reading your reviews!! I always end up buying stuff
