I am setting a a magento site with multiple stores for a client. The client has hundred of products and I am using Magmi to import them. Many of these products are Configurable and so I was wondering if it is best practice to create a separate attribute set for each product? As I understand it, this should give me lots of flexibility later on for adding attributes if required. However a draw back of this is a lot of manual work to go through, analyse the products and add their attribute sets in before importing them with Magmi... If anyone can give me some info as to what they do in these situations it would be much appreciated.
