Had Anti Rocks front and rear on my previous jeep; was not impressed, and would not do them again.
The only thing they were maybe good for was long rutted hill climbs that required speed to get up, felt like they were a happy medium between connected and disconnected and gave a better feel of control, but for everything else there was really no value to me. Limited flex on rocks and mildly annoying on road (body roll and a sort of floating/bobbing feeling on uneven roads, which we have a lot of around here).
Even flopped my jeep on it's side once climbing up on a rock I'd climbed many times before with a disconnected stock sway bar.
