I have been using Top Round roast sliced thinly with my food processor, although I think i will have the meat market slice it so I can have bigger slices.
To season, I sometimes marinade in soy sauce with salt, pepper, onion powder, garlic powder, liquid smoke, and anything else I feel like tossing in. I used to add Worcestershire sauce, but I found that it made it too sticky. Sometimes when I make it on the fly, I just use salt pepper, and garlic powder.
I take the slices and drape them over the rack and set the oven for 150 deg. convection. The thinnest slices (1/16"-1/8") take about 4 hours, and the thicker ones (1/8"-1/4") take about 6 hours.
Of course with sampling about half is gone by the time it's done...
