The lower the RC the "tighter" the car gets. Lower height are best used for guys with really big rear bars, or those looking to make sure the rear end moves as little as possible. I want/need a car that's more nimble and willing to rotate, but not loose or scary to drive. The Watts link makes the car more trustworthy to me and I prefer the balance at the higher RC height for what I do/the bar setup I prefer.
Sam,
Is my Progress Group rear bar considered big or small to you?
