All four of these are beautiful - I like this one best just because of the composition. From your explaination, the Lodima paper must be really nice. I haven't tried Lith yet, but it looks like this is the place to start.
If your just starting with Lith, try Foma 131 or 132. It's easier to get from Freestyle, and you can get Easy Lith or SE5 as well as Omega to start with. Good luck and let me know if I can help.
