I neglected to order an adjustable holder and so what I've got before me are a set of naniwas with their cute plastic bases and a DMT 325. When I use the DMT to lap the naniwas they pull such an intense suction that I can't get an easy figure 8 (or figure anything) motion going. I end up doing what I can on one end and then the other. In my fantasies lapping the stones should be easy. But in my reality it isn't.

Any tips? Less water/more water, get the holder for the DMT so I can give it more muscle, ...?
