So, I'm looking to hybridize this head: http://www.ringdoll.com/goods.php?id=732
With a ResinSoul body. However I can't find a body with the neck size (9.3 cm) that the head has. I'm a newbie to BJDs and don't know whether getting a body with a bigger neck (10 cm or so) or a smaller neck would be better (9 cm or so). I know that I will have to modify either the neck or the head. I don't know which one would be easier, so I'm hoping some experts (or anyone that knows anything about modifying resin) can give me a helping hand on this.
