Thanks for the photos. Nice trim job on the Hangars. Yup, they are a pita to get grill ready.
A good substitute for hangars (depending on price comparison) is beef flap meat. Supermarkets slice it into 1"-2" lengths but it's packed whole...either skinned or un-skinned in pieces about 1 - 1.5 lbs
Treat it the same way as hangar steak and slice it on the diagonal for plating.
