Did most of you guys change to the XXX-S from the Street Weapon? If you ran a different brand what made you decide to try the XXX-S? I am just starting in touring (I am an avid off-road racer) and got a sweet deal on a pair of IWC Street Weapons, but I noticed that everyone seems to have jumped ship on that car. Is the new one really that much better? As a touring noob, would I really notice it, or should I learn with the Street Weapon and move up later on? Thanks.
