Yeah, I don't plan to use Rocketloader at all. Haven't heard anything positive about it in terms of working with Xenforo.
One thing I was told by my host, however, is that once I enable Cloudflare.. the DNS servers have to propagate so I'm looking at anywhere from 24-48 hours downtime for some users. Is that to be expected? I'd be a bit worried about being down for some users for that time.
I had enabled it briefly yesterday, but quickly saw Google Chrome send me to the "blank grey screen" with a message that I could view a cached version since the site wasn't working.
