Calling with 33 vs an UTG raiser is a no-no in every book.

I only know of one book (HOH) which explicitly deals with this. I don't see how calling w/33 is a no-no whereas 77 isn't. The chances of getting set vs. set are only slightly higher w/33 and you have to assume UTG is raising w/44-66 to make you prefer calling with 77 over 33. So the very slight possibility of set over set only comes into play more with 33 than other pps in very few situations (loose UTG raiser).
This is actually one of the main things I disagree with Harrington on. I forgot the hand, but he says somewhere "this is a safe flop for top pair top kicker-the only set they could have is middle because nobody would play 22 here." It seems as though, if Harrington is right, then 22 goes up in value because of the deception. But I think this is irrelevant as people (correctly) play 22 to hit a set more often than Harrington thinks.
I should also qualify that I'm only talking about deep-stack situations in tourneys.
