Why lock and go 31 spline whe you already have 33 spline axles is a fair argument. But, how many people are snapping rear shafts on their X's? (Genuine question, i really don't know)

I know a 31 spline out of a hardbody is a 1.3" axle, the same diameter as the shafts in my trail rig. It has 35" tires, a 72:1 lowrange, a spooled rearend, puts out 275 lbs of torque, and weighs almost 5,000 lbs dry. In 2 years of wheeling I have yet to lose a rear shaft whether it be in the mud, rocks, or on the trail. U-joints and transmission mounts are another story, it seems that when I shock an axle they go out first.

So is it really that huge of a deal?
