Swamp Dog,
I think your fine........Dk is correct, if a glass limb is going to crack, generally is in a direction parallel to the limb edge either midline near the limb pocket or the edge itself will lift (generally the result of an unseen contact damage to the limb edge)

........if a glass limb breaks down suddenly and completely usually is it is a clean perpendicular break with no warning or a breakdown at an axel hole by improper drilling and these are very rare indeed.(and scary I might add)
If your limb was indeed cracked in the direction your picture shows I think you'd already be wearing your idler as a hat long before this.
