Probably the most flex intensive thing you can do is pull out of your driveway at an angle. It still creaks in the back.

For the guys that might do it, I got one of the 8lb kits from US Composites. I used almost the whole thing doing the rockers. Pour time is 45 seconds. It sounds like a very short time to mix, position yourself, and pour, but it's actually plenty of time with a little forethought. Use a drill powered paint mixing dealie and a funnel. AC duct tape, the metal looking stuff, is the best thing to seal off holes. Shit is magic.
