There are three good points you can take from the private / forestry commission road to hit the Slacks directly, at the very entrance near the gas plant (goes through a sheep field), at the livestock grid / Gavinburn sign / bins, and a few meters after the final livestock grid (an obvious main track doubles-back right, there's an interesting death scramble going left). More interesting than going up that interminable, draining road.
OpenStreetMap has all the trails (OS does not).
