I hear what you're saying but who can see the drive shaft close enough while its buzzing around to notice if it wobbles or not. I know you didn't come up with this statement, but I don't buy it one bit. If it wobbles, it's gonna wobble regardless if it has load or not. Load or pressure on the wheels isn't gonna change the effect on the shaft what so ever. I put my eb48 on my treadmill in neutral mode and had the throttle pinned and it didn't make a difference.
What I can tell you guys with certainty is that these shafts are NOT perfectly straight out of the box.
