As I gather from similar user experiences, even though Dolphin's latest versions run very fast, there are some situations where the hacks and shortcuts in 3.5 may give it an edge. I'm just speaking anecdotally of course.
It's alright to talk about 3.5 and how it works for you, just don't recommend it and don't ask for help with its issues
