Interesting-the lava flow basing system is a great idea 
Thanks, it's a good money saver for the large units as I needed only half the amount of figures to fill the tray up.
The yellow does contrast nicely. You say shit breaks all the time, how are you storing/transporting them?
Thanks it's not quite as bright it real life with the various other layers coming out of the lava.
As for storing and transporting they are all stored in KR Pick and Pluck cases. The real why they break is Restic and Cork doesn't seem to bond well.
