I personally would try and use it for a month or so to make sure you don't love it. It took me about a week to love my Speedy 30 (so much bigger than the Speedy 25 I had been using) - After that week though, I ended up giving my 25 to my daughter, I loved the 30 so much.
The BV and BH are both gorgeous bags. Even if you get a good price, you will be taking a financial loss so I would be really sure before you sell it that you don't really like it. I would put away all your other bags for at least a few weeks, use it exclusively, and just be really sure.
