I have an expandable Jandd wedge that holds quite a bit.
I had the cheater brakes, too, when I first got my bike. Found I never used them, so had them removed. Now, for really long rides, I sometimes use a tiny little wedge bag mounted backwards, just in front of my stem. I put things in there I rarely need to access on a long ride, like a couple tools, tube, cartridge, etc.
That way, when I'm getting into the wedge bag for a jacket or snack or something, it is just easier to get at, and I can carry a tad bit more on the bike without filling my jersey pockets, which bugs me a little.
