Thanks everyone! I certainly like the 32mm bases mainly as it gives more space to frame the model yeah, I doubt it's my basing Ragsta!
I got a bit more done amidst some other projects - the third, last, quad bike is now painted, as well as the medic rider for the second. I've yet to get a techmarine rider with bolt pistol so the third quad is likely to be riderless for a while. Ultimately then I'm about 5 infantry models away from calling the army essentially 'done'.
