You could always send some to me...
Lith is supposed to be had fun with, so use it! I have been using a very simple lith developer from Freestyle called Arista Lith. It's a single gallon kit and it takes forever to use up.
When I mix it, I usually make 3.2 liters. 1.5 liter water + 100ml part A and then another 1.5 liter water + 100ml part B. Then I mix those two solutions together.
I second the notion that the first printing session might be a bit dull. But after you save some of the 'old brown' and add it to your fresh developer, you'll get more interesting results. Sounds like you're on track. Keep in mind that it's more rare to find a paper that works well in lith than one that doesn't. Of the ones currently available, Foma Fomatone MG is great, Fomabrom gives some really gritty/grainy results that looks very interesting, Fotokemika Varycon (VC) and Fotokemika Emaks (graded) are awesome for lith but you have to be patient as they're slow. Most standard prints can be bleached and re-developed with lith chemistry if you want to see what goes on while the lights are on.
I also warm my lith developer up, but only to 75-80*F. It really speeds things up.
Have fun!
