Self extracting bolts are very nice, and should work with your cranks. They do make things easy when removing, just be sure to thread them all the way on. You will need a spanner wrench, or (another) special tool. Agggggghhhhhhh! Will the tool buying madness never end? I'd just buy the tiny little cap that slides into the hollow spline that allows a standard crank puller to work. That's what we use at our shop.
