It's not that bad (seriously, you should have seen Brasilia systems!), and I can understand him being a little worried about the gouge... That whole "fear of the unknown thing". At least with systems they tell you exactly what needs to be done, and cover EVERYTHING with excellent study material good instructors.

SoakingPilot, the fact that you're studying the gouge and worrying a little tells me you'll do just fine in the interview! They genuinely want you to succeed, and the SKW interview was one of the most relaxed and friendly I've ever done in my life.
