I should mention why I posted so many of Raul's images - he didn't use any sculpting tools back when these models were made. They were all created by hand. He only recently picked up ZBrush (and I think when last I spoke to him he was switching to Mudbox). Point is, there's no perfect mesh. There may be a mesh that's perfect for you as a user but will annoy the heck out of someone else.  All we can do is model, cross our fingers and hope for the best.
