If you ride the NTN, chances are you rip. Get the Rottefella NTN Ski Brake so your ski doesn't slide 1,000 feet down a face when you tumble after a 40 footer. The NTN binding comes with ski brakes, but this extra wide 110mm brake works for your fat skis so you don't have to bend out your brakes to make them fit. When you bend out brakes, you lose the reach of the brake, which undermines the purpose of the brake in the first place. Also, if you have the 2007 08 NTN binding, Rottefella recommends you get the newly designed brake because the bigger surface area won't wear down your boots like the 2007 08 has for some users.
