Hi David,
If you haven't upgraded to a larger bag already, are you considering trade possibilities? I have an excellent condition
Lowepro SlingShot 300AW. I'm in NW Houston area as well.

Not sure how much bigger you were wanting to go but here's the size comparison between the two. Looks like the main compartment is pretty close to the same. The main difference seems to be the additional compartment above the main on the 300AW.
Let me know if you're interested as I'm currently just using mine to store all my battery chargers and cords.
