Do those of you who have had a spline strip-out consider yourselves as aggressive drivers? or is it just a random failure?
Doesn't it seem like this problem is multi-dimensional? An under-designed hub spline pair will be more susceptible to errors and loads.

In your case, modest rpms, any gears, probably never loads the transmission input more than 1/4 or 1/3. Think of how many systems work fine until you start to reach the design limit--the Tacoma Narrows Bridge, which at the right high load oscillated itself to death.
