I think that rub will work great, but I too would leave the sugar out. I'd probably cut the amount of salt in half as well, but I'm into low salt, low (to no) sugar rubs. Nobody ever asks me why there isn't enough salt and sugar in my rub.
If you can fresh grind your own pepper, I find this makes a huge difference.
