I was debating looking it up in Rozental, and I thought that it would take to long to find the correct place. I will try and do it tommorow though, now that you've asked.

As for distrust. I read the whole section about usage of который/какой/кто in Wade and I have to admit that there was some (small) parts of the text that didn't make much sense for me. (Such as an assertion that the choice between кто and который may be based on the gender of the releated noun/pronoun. The examples that they were giving while were correct on their own, didn't match the big picture.) So I can see where you are coming from with this distrust. On the other hand people who wrote these books spend lots ann lots of time studying the subject and they are very learned and one has to respect that.
