Assuming your asking because of handling issues in the front?
I don’t have any experience with a nimble but have done a ton of riding using 909 & 999 zipps. The handling is great with a 404 front- pretty much a non-issue in most wind conditions. My only point of comparison would be the HED3 front and that was handful to manage in any solid wind - I ended up selling my trispokes after trying a 404 front. If the nimble is anything like the HED3, the difference would be pretty noticeable vs. a 404. I’d imagine even more so for you since you only weigh a buck thirteen! 
Ton of people with Zipps out there…i’d suggest borrowing or demo-ing a 404 before buying, if possible
hope that helps
Well, I guess it depends on the fork you have on the bike. Spoked wheels like the Nimble fair rather worse than a 404 if the fork blades run close to the wheel (narrow) as the blades cause interference with the wheel, while they tend to be pretty close if the blades are widely spaced. I have a set of Crosswinds and find the front plenty fast with a disc in the rear, but I have to admit that my fork blades are about as wide apart as can be. I have not really done enough testing with the Nimble compared to my 404 to know which one is best. The 404 (tubby version) will be lighter than the Crosswind, if that is important to you.
I have a HED3 front, Nimble Crosswind front, and 404 front. The HED3 is the most difficult to handle, although a disc in the rear certainly improves matters. I find the Crosswind much less of a handful, with the 404 more or less similar. The Crosswind, like the HED3, seems to have a pulsating feeling coming through the bars, which the 404 does not have, but that does not influence the handling as far as I can tell.
