Yay - just saw on the GW website that they changed the size of their Knight to 6" instead of 8". Pew - had me worried there for a second, would be quite difficult to add that much extra size to the Leviathan. 1½" on the other hand is just a fun challenge, that I'll be looking forward to. A bit of extra spine and a litte extra armour plating should easily give me an extra 1", which should fine together with the GW one. Hurray!!!
