During operation the grease is slung to the outside of the movable primary sheave and I haven't found more than a light coating of grease in the weights during inspection, after operation.
I don't think the grease adds enough weight to affect the timing of weight movement in the channels, and any grease on the weight(s) becomes uniform so any effects from grease are uniform over time.
As for options, I use round weights from Yamaha and from E.P.I. in varying weights to influence up-shift timing. The grease is a pain during handling, but the greased weights work for me.
