I'd like to make a few general comments.
I live in the Middle East and have some experience with Arabian fragrances. Although my knowledge about these perfumes may be a little greater than the average, I'm certainly no authority. So take what I say as opinion, not fact.
Rather than comment on specific Arabic fragrances I'd prefer to talk about my experience with them in general.
In my opinion there are quite a few oud based fragrances that qualify as light or fresh. I don't know of any oud aquatics unless Aragon, as The_Good_LIfe has mentioned, qualifies.
But among Western fragrance lovers oud has this connotation of being heavy or dense or dirty, and to me that just isn't the case. Of course it can be, depending upon what kind and how much is used, and what it is blended with. But I think many oud fragrances are light and airy, and even refreshing.
Remember that these fragrances are very popular in the Middle East, where it is very hot most of the year. Does it make sense that Arabs would wear something heavy and stifling in this heat? No. Like them, I'm finding that oud based fragrances are lighter, cleaner, and more invigorating than you might think. They cut through the heat and uplift the wearer.
For example, I think most Montale ouds, even Black Aoud, are light and airy, especially in comparison with some of the oils, which are considerably stronger. I never feel that Montale ouds are heavy. They have an airiness, a lightness, a clean verve, that I actually find refreshing and enlivening in the heat.
I don't really have much more than that. I just thought I'd throw that out so perhaps you could look at oud based frags in a different light. Ouds can be light and clean, but just not in the same soapy or freshly ironed sense that some Euro fragrances are.
