Tank bag?

I'm planning a little trip this summer on the KZ around the great lakes and I'm looking for a tank bag that will work good because I don't wanna get saddle bags. Would prefer to only have to take a back pack, tank bag and maybe my net for the pass. seat to carry things. Any suggestions for a tank bag? My bike has the 3 gallon tank by the way.

There was a bit of a discussion on tank bags here.
among other things.
