I did a similar one to eschatz's and the first 5 gallons of 10 were excellent but not all that close IMO. Granted I've only had a few bottles of it to compare. My second 5 gallons of the batch were aged longer and I doubled up on the dry hop. It really improved the beer and from memory I think it was much closer to the original. Really does not matter as it is a superb drinking IPA as brewed.
