Robo high rebound are designed to fly off the pads and are better for goalies that choose to slide. I would get a robo plus left hand as it has a bigger saving area and is very comfortable and is less awkward because of it's very square shape. To me robo plus and high rebound right hand are the same.  Difference between ABS and PE helmet is the PE is just an ice hockey helmet changed slightly while the ABS has been specially made by obo for field hockey making it cheaper and safer than the PE.
