Maybe try replacing the Static.ini in HSFX with the one from 4.09. (or create a mods folder and override that way)
It should work Ok for map building (although you won't be able to use many of the new maps obviously whilst you have this enabled)

This has the advantage that you can then add only the objects that you need and keep track of them all at the bottom of a clean static doesn't it.

I have never tried it but if its a question of freeing up memory, has anyone tried this with an empty/almost empty Static.ini ?

I actually tried this already, by deleting about 300k from the static.ini (most of the channel objects). I didn't notice any improvement though. It might be because HSFX loads them as .sfs files anyway.
