One other thing you need to consider besides the shock, is the reaction torque when you try to steer - you will notice this most on fast/heavy (high angular momentum) disks - and most particularly when they are not horizontal.

I would say most spinners have welded on teeth - and I know one or two have moved from bolted to welded. We of course, having steel teeth on a plastic drum do not have that luxury! If the placement and type of bolts are appropriate - bolting will not be an issue. It gives a number of advantages like being able to make rubber teeth for friendly fights and being able to taylor the tooth profile to different opponents.
