The Super Fatty SL with its super stiff Fatty blades, comes with 5 damping positions to choose from. No lock out. A bit heavier than Fatty and Ultra.
The Fatty M is a classic. Light blades with a simple friction damper, coil spring combination. Great for upgrades!
The Super Fatty D and DL are identical except for the decal. They come with super stiff Fatty blades and a lock out feature. A bit heavier than Fatty and Ultra.
