that second picture looks a lot more flexy!! 
Flexy doesnt mean better. Im not knocking Erics rig cause I like/liked it both ways.

We went too hells revenge two days with two different groups of trucks. The only 2 IFS rigs were chunk and I. Chunk has some of the worst flex ive ever seen, yet he was the only one that I saw drive out of mickeys hot tub.

OR to drive up that slickrock wall in hells revenge...

I couldnt do it either, but my point is, an IFS car did. Theres something to be said for stability.
