If that’s your end goal, and you are using these as a training tool, then yes, marsblade and asphalt wheels, paired with some cheaper bones bearings, or even another brand you find cheap, are ideal. You don’t want to spend too much on bearings for outdoor usage as they will get dirty and have a bit of water uptake from puddles etc, and even with cleaning will break down faster, just something decent to get you rolling.
