Oh definitely Barrels ftw
What is the scale? And how much do they cost? Just curious, also what do you use to make them?
The average one is about as tall as a can of coke, i use balsa and "bits" to make them, by bits i mean anything that looks right.
for example the chest and back on these BK's were cut from a container from a self saucing pudding bowl, i saw the curve of the bowl as i was throwing it in the bin and had a light bulb moment
I spoted the perfect curves on both the X and Y axis in the bowl and my BK's were born from that .


The hex board should give an idea of scale

As well as plastic stock from the hobby shop
The cost is measured more in time than money, but i guess about 30 bucks each, but that can vary.
SciFi modelling is a passion of mine, and i was hooked on the BT genre from the first tabletop game.
