So at the risk of jinxing myself, I haven't run into any issues with my HR34 and three C31 clients. (The HR24 has been rock solid too.) However, reading these forums makes me skittish. It's almost like I cover my eyes wondering when the scare is going to come. I know that problems are more likely to get posted than positives in such a forum, but I'm wondering, how many people around here have perfectly acceptable HR34-C31 combinations?
