I'm with Button, I really don't think it makes a hap'orth of difference which grease one uses, so long as one does it regularly and swaps to hardchrome kingpins as soon as the originals wear out - which won't be very long if one neglects the greasing
But a Moly grease is a good choice. I'm currently using Red'n'Tacky, which seems a bit thicker to me.
