That is an awesome pipe! I wouldn't say you bought it because of the speck of plateau on the heel though. The plateau on Ember's pipe makes much more sense, and I agree with zack24 as far as eliminating that spot.
Good call. That pipe has been available for a good while now. If it didn't have the spot it wouldn't have lasted a day. I'm certain the pipe wouldn't have left the bench if it was compromised, but the smoke is only part of the joy of the pipe.
