No offense, but I think it's time to update your understanding and expectations of modern composites. Today, well designed composites won't shatter when they fail, and they'll have far higher impact resistance, regardless of direction, than typical aluminum frames. Start digging, and you'll find info on the subject, some of which is 12 yr old stuff from Scot of Ibis. There's a lot of new stuff out there talking about carbon rims as well. The old thinking that "Carbon snaps", is dead and buried.
I'm not a composites engineer, and I don't have a test rig in my garage, but I can tell you from MANY experiences, that a big sharp hunk of limestone makes a hellacious baseball-bat-cracking noise when it smacks a Mojo downtube or chainstay...but that's it... no damage. I've also seen plenty of aluminum bikes snapped in two at the head tube, bb area, seat cluster, etc etc. An impact that will dent the ***** out of aluminum, but leave it rideable, will typically make a mark in the clearcoat of a good carbon bike, but that's it.
Other brands' uber light carbon race bikes may be fragile, but not the Mojo... and certainly not the HD.
