Personally, I think you have the right approach right now. Mostly because you write that 'it sounds fine'
On the other hand, this is how we learn. While I agree that bi-wiring is questionable at best, I believe that the process of experimenting, paying attention to the results writing about it and getting feedback is a great way to learn first-hand what it is you really want out of your system.
No matter what- have fun!
