Besides the chocks, I think that the fact the jack slipped off the wood caused the damage to the stabilizers. I myself am weary of putting anything unstable under my jack foot as it can easily fall over.
I find that when I extend my jack to the highest, the foot moves forward an inch or so; this action on a small piece of wood (4x4) just spells TROUBLE as it can easily tip it over.
On my sloped driveway I use a cinderblock with the widest side down, at a fore/aft placement, to give the foot room to 'walk'. I probably will eventually get a taller jack (24") to accomodate my sloped driveway and higher hitch ball on my Ram and this way I won't need anything under the foot.
