Responsive themes known to run well with WPMUDEV plugins

Hi there,

I just subscribed for the first time to WPMUDEV and I wanted to know if those of you who have been using their plugins for a while have specific sources – whether free or commercial – that you mainly go to for your responsive themes (especially if they are known to play well with the WPMUDEV plugins).

Some themes can at times conflict with plugin functionality and vice versa, so that’s why I am asking.
