A "yay" from me.
I use an old TTW ring that weighs about 2.5 lbs. and would not be without it. It resolves any warp in a record (and more have a slight warp than is thought). It also adds flywheel to the platter which helps with speed stability and therefore SQ. By this time I place it down quickly without thinking about it. Though I use it on an old VPI platter that could take more weight, it is enough and, at 2.5 lbs, likely not too heavy for many other platters.
One must then just be a bit careful about placing the stylus. You don’t want it running into the ring. I have modified my arm rest to place the stylus perfectly. Solves the issue.
