In one of the Green Ronin Modules (Black Sails over Freeport IIRC) we fought these intelligent dire ape like creatures on one of the Pirate Isles. They used a mancatcher type weapon with 10' reach. Required only a touch attack and they made a opposed grapple check or you were immobilzed, and they had something like +19 Grapple. We were around 7th-9th level and most of us couldn't win an opposed grapple against +19.
