I have used one very similar for years. I use a commercial dry Italian 5-herb blend (oregano, basil, etc), a little less red wine (1/4c, cabernet only because that's what I prefer to sip), 1/2 the EVOO (2 Tbsp), at least 2 TBSP of the balsamic vinegar, 1 tsp each sea salt and fresh ground pepper. Mix it all up with a whisk, I usually only marinate about 5-10 minutes before grilling, but longer is fine too (even overnight). About 2lbs 3/4" or so thick steaks, three minutes on a side on the hottest grill possible, rare to medium rare.
