I think that because the results can vary so much from person to person with lith printing, you really should buy a bunch of different papers and experiment and see what you get. There's another thread going on right now about Slavich papers and lith and just by reading it you can see that different people get different results.
I tried the Slavich paper because it had been announced that Forte was ceasing production of papers and so I bought 6 different papers to try (in packs of 10 and 25). What I got was 1 paper that I really liked, 3 papers that I could possibly see me using for certain negatives and 2 papers that I really don't like, one of them being Fotokemika Varycon. If you look in this thread alone you will see that there are some big fans of Varycon in lith, I'm just not one of them. That's why I say you have to do some printing to find out what works best for you.
