Jon, no personal experience but Clayton Round Rebel T NFAA/Supercharged Outlaw fitted one this winter, his first meeting was garys picnic, but he's done some damage to it already not sure what yet tho, maybe best buying a cs1/2 and a bruno if you dont want to set a clutch up all the time
Spoke to Claytons brother Chris today, apparently it took all the teeth off the output shaft within 3 runs he said its a bad design when you look at it
Just wanted some feedback first, better google it and see what people say
