I had the smaller pulley on the C32 for some years, was the only car I had.. I have had the 84mm smaller pulley on my CLS55 for about a year and half and now just installed the 77mm pulley. Car runs great.

I've been running mine daily with a 77mm clutched pulley for maybe around 8 or 9 months now, no issues.....just make sure cooling is top priority, summer can be a killer

I have the S class so the bigger h/e is not a top priority. Although I'll be doing the ic pump soon. With all these stories of the broken pulleys, is it really just a bad batch of them? Or is it the installation?

the design was updated a couple times. there really hasn't been a higher than usual failure rate since. even the stock pulley is known to let loose, so i'd recommend getting a pulley shield from latemodel21

I daily drive mine with the 77mm fixed pulley. I'm going to assume that I put more miles than most members as I drive my car for work as well and I love having the fixed pulley on there... the throttle response is so nice to have. I went with the fixed pulley originally though because I didnt want to deal with the clutched pulleys exploding. For reference I've put 30k miles on my car in the year that I've owned it.
