I have g5 and i like you dont like the knee to calf,
what i do though is take the stock knee wing off, then get a piece of sticky back velcro - fold this ove on itself on to a piece of cord, i use paracord then i lace this tab into the pad, where the stock one goes,
what this does is allow a tight knee, but no digging in from the knee wing, i then have the lower calf strap loose and just a toe tie, note i dont use the webbing clip strap on the knee.
ill try and get pics tonight
