According to a recent whitespace Bell/Boeing presentation, the current recommended solution for 'busting out' of VRS is to apply 2° nacelle tilt using the maximum (=normal) rate of conversion. IIRC, this results in 400–500ft altitude loss. The V-22 is susceptible to entering VRS at descent speeds between 2000-5000fpm and airspeeds up to 40kt.

Not all the way forward to 0°, since this would result in proprotor ground strike. The civil BA609 shares the same drawback.
