I didn't do an IPA, as Dogphish said, not a great idea with all those hops, BUT I did do a sort of Old Ale type thing... it was years ago (1993?), but IIRC, it was around 1.065 +/-... the basic wort was similar to Rogue Dead Guy, but with about 15% lower bittering. There were some other Christmas-y items, a bit of ginger and a little cinnamon. Used about 2# of cranberries, threw them in boiling water to sanitize them... they split in the process. Strained them out of the water and dumped them in my ferm just before the wort went in. The resulting beer was amazing, BUT it took a while to mature... couple months + in the bottle before the flavors had blended/mellowed
