Being able to buy individual sprues is great for me because I don't always need the a full set.
These are lovely figures, well animated and with lots of options in terms of heads, weapons and poses. The faces have lots of character and represent mature, gallic/celtic horsemen.
I have used Victric galls for my gallic army but needed to change its composition and only needed 3 figures, one to use in a command stand and two to make a light Cavalry unit so getting a sprue was more cost effective than a package of 12.
