I am not really a great fan of the Dwarves, and I admit that I hardly ever played with them in the Edain Mod 3.8.1, nor am I really an expert of the Dwarven Lore.
But I really have to say that I like playing them in the current Edain Mod 4.1
I like BOTFA Dáin concept of the Iron Hills, but I would say that my favourite subfaction is the 'Blue Mountains'.
You can use all the Dwarves of the Dwarven Company from the Hobbit trilogy, and the heroes themselves are very Hobbit-ish, probably the most Hobbit-ish ones among the three subfactions
And the Blue Mountains always give me a feeling of relief and safety, probably because they are one the most safest places in Middle Earth during the War of the Ring, and because they are situated in the far west of the World, very closed to the Great Sea
