Never done it, but maybe I would try this for an experiment, Marinate 3lbs of steak tips overnight.....
Marinade: 1+ cp of soy sauce, 6 tb canola ,6 tb brn sugar, 3 tb cooking sherry, 3 tb hot sauce, 2+ cloves garlic minced, 1 tee each of ……ground ginger, pepper, dry mustard, 1 tee + of onion pdwr.
Cut your bacon strips small so they just fit around a steak tip, then wrap bacon around each tip sliding several of them(maybe 8 to 10) onto wooden skewers so that it will be easier to move them.
Smoke them at 250 for 90 minutes or less, and serve:-)
