Had a chance to ride the Mark III over the weekend and was very impressed, but I've heard a couple questions about lateral stiffness with the DW link. I weigh around 195 and I ride aggresive XC in SoCal with a lot of climbing. Has anyone had the chance to spend a lot of time off road on the Mark III? Has anyone ridden it next to the 575 / Reign or Heckler? Any input on the Mark III or how it compares to other bikes in it's class would be great! Thanks!
