Sculpish IPA Clone Attempt

Continuing on my purge of rather old hops, I decided to make something like the great Sclupin IPA. A clone recipe was posted in the latest issue of Zymurgy, but I made some ingredient substitutions. Also the hops are from several years ago. (Sadly my proclivity to buy them was greater than my proclivity to brew with them). In any case they probably have less AA and overall hoppy goodness than would be optimal, even though they have been stored in the freezer the whole time and are in unopened vacuum-sealed bags.

--------- 

7/2 - Starter with re-used Sac. Trois. 1L.

7/4 - Brewed. A little high (152F) on the mash temp.
 Split my sparging into 2 equal-sized batches instead of 1 big one. Preboil OG was ~1.057. Post-boil was 1.068.
Got ~5.5 gal into fermenter, leaving about 3/4 gallon of hoppy trub in the kettle. 
Cooled to 60F. Oxygenated 60 seconds, pitched decanted starter. Placed carboy in 66F ambient basement.

7/5 - Good fermentation activity. Lots of krausen. 

7/6 - Moved to 70F ambient area. Still good airlock activity and krausen.
