Just go out and get yourself some Protek, Intuitive, Shogun or Lightning sliders that are specific for your bike and let this thread die. All sliders are going to be about the same size. The longer the slider, the more leverage it's going to have on the mounting point. It's going to be more likely to bend of fuck your frame up.

Does it affect you that much that some random guy 1500 miles away went and paid his own money for a 1000?
Do we really have to fight over who uses the back brake or not?
Do you have to argue over stupid pointless shit on the Internet?
