or you could go with the dashboard genie sooper deluxe angle that down below your bars and attach the bag to that. That way you could just drop it a little bit and/or adjust height as needed. I have two of the smaller dashboard genies to raise my lights above my bag, but have been thinking about using them to lower my bag height instead.

I have a Jannd Extreme front rack that I really enjoy, but it's a bit pricey.
