Von Scheikert VR4-Jr/ lead shot?

I have heard different thoughts about the amount of lead shot to add to the VR4-Jrs. On Audiogon a while back a lot of people said 25 lbs. per speaker. In the manuel it recommends 50 lbs. per speaker. One person wrote me that he din't prefer the speakers with the lead shot. I think that it is important to have it. Since a little time has passed how much do you prefer? Thanks
