There seems to be a general feeling that putting thicker pads under the LG and stabilizers cuts down on the wobble. Shorter leg extended means less "wagging" around. I don't think there is really any to prove whether or not that is true although I am sure that plenty of folks will come out of the woodwork to say I'm wrong.
That said, I took a 4x4 PT fence post and cut it into 12" sections with a chainsaw. Gives me 8 blocks each a foot long. I put two of them under each landing gear pad and two each under the stabilizers.
Besides giving me 4" of height, this spreads the ground load over an area 12"x8" so everything is less likely to sink in. 96 square inches instead of 25.
I'm not personally sure that just stacking the little yellow Leggo blocks up would help much. I have a set and they seldom come out of the basement. The 4x4's are light enough to just pick up and toss into the back of the truck, but heavy enough that they will not fly out at speed.
(I have a king-pin tripod and install it if we are going to be in one spot for five or six days or more. The wife thinks it makes the bedroom more stable and if that is all it takes to make her happy.........)
