Sounds like you have a perty decent little squirrel dog to me.:biggrin: I tend to like a dog who hunts by scent first and sight second but my dad prefers them to hunt by sight as he does not like to walk a long ways for a den or nest, if the dog trees you know the squirrel is there!! I have had several Mtn Curs and I have 3 Feist (and my folks have two fiest). Out of all the dogs we have had, none of our Feist hunt stricktly by sight! Now I have had several Mtn Curs who would only tree by sight for a while. It seemes as though they will tend to learn what the squirrels smell like and will start treeing a little more on just scent. But these dogs I had never did tree entirely by scent!
You may find that as he gets a little older he may start treeing a few by scent alone. OR, you may have just what you are seeing! If you are happy with the dog I would not worry much about it. For instance, I have a male Feist that locates squirrels like no bodies buisness but he don't bark much. He is learning but I don't think he will ever "blow the top out" on a squirrel. I love the dog, the way he hunts and everything about him except the closed mouthed thing, so I will hang on to him!
