Anyone that said that organics eat flywheels is retarded.  I've had ceramic and copper pucked clutches beat the hell out of flywheels and pressure plates, but never an organic disc.

For my performance car needs, I find myself coming back to ACT for clutches.  They've always done the job at a good price, haven't ever faded, and have held up to years of abuse.  But, since we're brand loyal to Marlin, I guess you could go that way.  I have no personal experience with Marlin clutches, so I can't personally say. 

BTW... you need to post pictues.
