Bit late to the discussion, but I use EBC HH pads on the front and normal on the rear. Used to have HH on the rear too, but the bite and stopping is a bit too much when combined with better brake hoses. HH ones do eat disks faster than the normal pads. Stay away from Gold Fren, destroyed a front set in 4k miles and the rear wasn't much better.
I recently changed pads on my DR-Z, went for EBC TT (enduro) organic pads all round and I quite like them. Slightly less bite compared to HH pads which makes the slow speed braking a bit smoother/controlled, but still significant stopping power if you brake harder. I don't expect them to last as long as HH pads, but even if they last half of what HH pads last me I'd live with it (I think they will last longer than half though.) They also appear to be easier on the new disks I fitted than what the HH pads on the Strom was. I might even fit EBC TT pads to the Strom next time I change.
