Hi Mirkoni,
Be careful not to let the nose ride up when reverse is selected.
The turbulent airflow around the thrust reversers causes an increase in pressure under the wing. Since the engines are mounted inboard, the effect on a swept wing is to cause a mild nose up tendency. It is easily controlled by nose down elevators.
Why not wait for the nose gear because of these pitch moments?
Since it's not a problem to control, if you need Reverse thrust then take advantage of it early. Also wheel braking causes a nose down pitch, so just fly the nose wheel gently onto the runway.
