My son has quite a few hours on X's.
As I recall he said that the brakes are excellent and with full reverser buckets it is necessary to push the nose down otherwise it (the nose gear) will be off the ground again.
This caught him out on his first sim "landing" of the G-V, where you have to pull to hold the nose off.
I'll ask him about the other stuff when he gets back from vacation.
