so my wife keeps on buying Flank Steak for me to grill for some reason I don't understand. Must be a childhoold trauma or something... 
I'm not seeing it. Seems awfully tough and stringy to me even grilled rare. Yea, yea, cut it across the grain and all that, but still doesn't seem to hold a candle to Top Sirloin etc IME.
Are there easy ways to salvage this cut for grilling -aside from 20 days papain marinades and the like-?
