Sorry for the late reply, I have experimented furiously over the last 24 hours with an assortment of lubricants (all to the image of Griff's grand final winning goal). Please see my findings;
The preference of noodle grease really depends on the stroke rate and the emotion of the pull. As we all know they vary from the furious tug, which I personally label "the vengeful Griff" to the more majestic, somewhat graceful "Griffantasy". Both enjoyable in their own element.
For the vengeful Griff, I would highly suggest something industrial and robust -

The Griffantasy is an easy one. Gypsy tears - sourced from directly from Gosford if possible. While using this for any non-Griff related self-gratification would otherwise instantly lead to HIV infection, luckily the Griff factor which occupies your thoughts in the process acts as an impenatrable antibody that not only protects you from disease, but acts as a penis growth hormone and somewhat strengthens your bell-end with Griff-like capabilities. As an added touch the saltiness of these tears add an unmatchable tingling sensation in and around your Jap's eye.
Happy yankin'.
