On our Cougar, we used x-chocks and Bal stabilizers, plus a home-built diagonal stabilizer bar from the bottom of one rear scissor jack to the top of the other - very solid.

Our Laredo came with the Ground Control 3.0. We don't use the x-chocks anymore as the auto level removes a good bit of weight from the tires rendering the x-chocks less effective. We do still use the Bal stabilizers on the landing gear and we place rubber chocks fore and aft under the tires. Very stable.
