Who deals with large assemblies and how do you handle those large assembly designs?

In Solidworks we do have several tools that can help you handle large assemblies.  Namely Lightweight, Large Assembly Mode, Large Design Review, Speedpak and some of you will likely manually create simplified sub-assemblies.  I am wondering who uses which tools in order to speed up assembly performance and which experience you have got with those tools.  Or perhaps you have other means to speed up your assembly design process and I would like to learn about it.

Any feedback is highly appreciated!

Kind regards
