Actually, the CSL aircraft are even simpler than FS98 aircraft. You gotta see them to get the idea. But, anyway, personally, I plan to keep them installed for a while, just to see the actual impact to the sim, and especially to get a good view of the show! I can always flush them if I decide to later.
If an Observer want's to see the diversity of a gathering like this, it might be a good idea to install them. And the file size isn't really "super huge".
