I went for the Hot Zone aug, and I didn't bother going back. XP was only OK.
They goofed up, and this is actually the 70-75 hotzone, w/ Valdeholm being the 75-80. The dev in charge of making them acknowledged such when they were initially revealed, but went on vacation and the dev who ended up implementing them didn't "get the memo."
