RPGnet looking for Barbaric opinions!

Hi! There's someone over at RPGnet looking for opinions on the Barbarian series. I've been giving him some (obviously biased) info, but I haven't actually used these books in a game so I'm coming up a little short. Is there anyone who's actually play-tested them, or used them in a regular game who could chime in and help?
Here's the thread
