I've owned three V-Stroms and put EBC HH pads on two of them (the third had a Nissin 4-Piston upgrade by PO). In my opinion, just switching from factory pads to the EBC HH made a huge improvement. With the stock pads, I could "coast" at 40 MPH and practically stand on the rear brake with no effect. With the HH pads, I could lock the rear if I really tried, but they were easy enough to modulate that it was never a concern.
I never tried the braided stainless steel brake lines, but I've heard those also make an improvement in combination with the HH pads. You can always add these later.
The V-Strom with the Nissin 4-Piston upgrade stopped well, but I never thought "Wow, this is better than the HH." Of course, I'm not a track day rider, just an old retiree who does venture "slightly" above the posted speed limit when it's safe.
My humble advice - try the HH pads and go from there.
