At 42" the intensity would have to come down or the restraints completely redone for smaller children. 42 or 44 inches would probably send a better message that the ride is meant for kids since 46 kind of gets lumped in with 48.It's fault, I think, is that 46" is a bit too high -- not saying that there isn't a reason for that, just that it would be even more awesome as a 42" coaster.
