Chris,
Alex is right on the money. Stock torsions and good shocks.
In general you want soft suspension and firm valving. Think about it, if the wheel doesn't stay on the ground it's of no use and dangerous. A soft spring insures that tire contact is always maintained. Too stiff a spring and the wheel looses contact and problems arise...especially in corners. Pick up a couple of Carroll Smiths' books, they're gold. I can lend 'em to you if you wish.
In general I find the softer I make the suspension on my rides, the better it rides and handles...maybe It's just the old man in me talking...
