[@FalloutJack]Actually, I was thinking of when he ran off of the cliff and survived by hitting branches without injury.  Mostly that was because he caught branches or because of his suit, though, so maybe that was more agility than durability.

Similar to how I'd set his mom's durability at C instead of B or A even though she survived a missile strike.  The suit was shown stopping small rockets when she first saw it so it has to offer a bit of protection.  His suit could be very similar instead of just being low friction, and highly wear resistant.
