Since the sculpts came out, there was another range released, still sculpted by Nick Lund but this time the figures were slightly larger. This new set was released in the early Nineties and is very useful, as the larger wolves can be used for bigger mounts of the leaders.
The sculpts are very nice I think and sum up the essence of wolves very well. The long snout and long fore legs with big paws are better than a lot of more recent sculpts I think and have a lot of character.
The only slight negative aspect maybe is they are laden with equipment. The Wargs of Tolkien let the goblins ride on their backs as a kind of mutual arrangement and would definitely not allow equipment to be packed onto them. However, maybe they quite like the idea of having a bit of extra armour on them...anyway, they are definitely the best large Wolf mounts around at the moment that I have found. The bonus being a lot of them are free, being figures from my childhood.
A unit of twelve should be enough and due to the size of the wolves, they will probably be classed as an assault unit rather than a scouting one.
