V3RR and M3RR are great figures which work well with Posers built in reyes smoothing.

I actually like them so much I even built a David-RR and SP3-RR once by transferring the David and SP3 shapes as FBMs from V3to V3RR.

Also all of my custom made figures are based on a hybrid mesh I made by putting the V3RR/M3RR head on a regular high res body, resulting in a 45.000 mid-res figure. (Best of both worlds)

Of course if you need lots of muscle or other body detail, the reduced resolution bodys are notacebly "softer" than the regular ones, but for most youthful face morphs the lower res heads are detailed enough.
