I've ridden std. suspension, xtra-12, xtra-10, edge, and IQ. The Edge and IQ skids are almost identical, only difference is the width really. The geometry of the Edge is completely different than any previous model skid too. The Edge rides better by far; and although most people say otherwise, I think the xtra-12 rides well too. Just needs to be setup right - but it's not a jumping skid or one that takes a beating well.
You can get and Edge for cheap enough nowadays.
You don't have to flinch for me to know that you're scared.
