I had that beer in bottle a few months ago. Very nice and restrained English version of an American IPA. Even my american hop disliking wife thought it was very good. I prefer a bit more hop bittering and flavor, but this is a good one. The recipe looks like it would be about right. That crystal would either be a 40 or 60 L variety in my estimation. I'd say the bittering was probably in the 40's, not too bitter.
