I've always held the philosophy that the stuffing box should not drip unless the shaft is turning. So I would want mine to drip once in a while when I'm motoring but not when I'm sailing.
I haven't heard of the GFO/GFU products, they sound good, I may try and get some. I still use the old waxy flax stuff.
