just tested 2.0, and it looks like it has everything updated to inlcude the same options as HSFX and even a switcher to activate HSFX mods.
I was particularly interested in some of the optimization they are working on. So far, they have included modified exe files to better enhance the game for when you are near cities reducing stutters, and allowing for better frames rates in clouds.
In a way this is a more unified version of the two packs. I'd say its worth the download, and actually if you already have 1.8 you can patch to 2.0 relatively faster than patching from 4.09m.

I quite like ultrapack, has everything HSFX has, plus a few more goodies.
