I have three of the kinda terrible and small metal Genestealers, so that is not really an option. The Overkill 'stealers are by far the best looking of the bunch, but I had only four of those. I do have just shy of a zillion of the other plastic versions. So I did a lineup to compare and contrast.
The Overkill version is on a 32mm base, which works well for the whole big arms thing 'stealers do. I put the 5th edition one on a spare Blood Bowl slotta base which is 32mm. Then I tossed in a 'stealer from my old Space Hulk set.
I liked how the Overkill and Space Hulk 'stealers looked like they were related to the Patriarch. So the 5ed Genestealer was out and the Overkill ones were in.
The Overkill Genestealers are a bit hard to come by. I traded for a few, and won a couple of auctions on eBay to bring my total up to ten. I decided to use ten of the older Space Hulk minis to fill out my force of twenty. Oh yes, this little project was getting a bit crazy.
I carefully cut the 25mm bases off and put the old timers on new 32mm bases. Then they got a repaint. I was worried the new coats of paint would pile up and make a blob-like 'stealer, but I managed to thin the paints enough for this not to happen.
The end result was a bit of crazy went a long way. The force of twenty looks great as a cohesive unit, and like they belong with the Patriarch.
It's that what a good Cult is all about. Belonging. That, and bathing in the blood of the unbelievers.
