Naked,
I am using a TrueNorth Loadmonster (http://www.truenorthgear.com/product_detail.php?path=5&p_id=60). It is a "fanny pack" with shoulder straps. For me, it is better than either the "fanny pack" (I previously used the same one you have) or the day pack I used to use. The side pockets carry Nalgene 1L bottles with a metal cup, and the metal cups make it easier to get the bottles in and out. Thus I carry two bottles and two cups. I like the Practical Tactical cups (http://www.practicaltactical.net/prostores/servlet/-strse-237/MSR-Stainless-Steel-Nalgene/Detail). If you are upgrading, please give these items some consideration.
