Well to me, the socket and ball was the attractive feature of your bases, Matt.  I can easily remove the base for storage/transport.  Tilting the mini was not a big thing to me.  If it's going to be a fixed base, ie glued to the mini, then I may as well consider using someone elses's bases.  Corsec's 3-piece bases might be good option, despite it costing over $2.50 a ship to base them.
