The Razr X Black head is not as wide as the x hot, so the x hot should be a more forgiving iron.
I don't know if the lie angle would change the point on the face where you are contacting the ball. However, the toe of the club might be contacting the ground and opening the face. In other words the club head is tilted down toward the toe instead of being level with the ground.
In that case you would need a more upright lie.
