For the trails I ride and my weight (195 lbs), I keep my tire pressures on the carbon wheels a minimum of 28psi.

So not too far off on what I was typically running.  I think it was just a freak accident and but I worry more about side impacts than what happened this time. 

I forgot to include me weight, 165lbs.  Probably +10 with kit.

Either way, this was likely a freak occurrence it seems.

Agreed.  I weigh 165lbs + gear.

Need suggestions: The nut on the rear thru axle somehow nut got loose on transport to the trail.  It fell off and no luck finding it.   

There was talk somewhere on the forum of someone who lost theirs also.  They ended up creating their own and it looked really good.

Update: went to front and back Maxxis Ardent 2.4's; too many sharp rocks

Cliff Notes: hole in two ardents and one Icon

What do you think? Need some repair or will it be good?  I think it will be good.  Going to add some Rubber 3m tape. 

Me personally, I wouldn't do anything with it.  However, if you think it might develop into a problem you could try applying some clear nail polish on top of the scrape.  It may keep any of the fibers from coming apart, but that's only if you feel you want to do something with the scrape.
