2 master cylinders, 200 miles

yes that is right i wasted 2 master cylinders within 200 miles. I have heard some say that some of the heavier aftermarket clutches are too abusive on the slave and master but has anyone ever had this much of a problem? I run a ACT Xtreme pressure plate and a 4 puck disk. Has anyone put on some serious miles with a heavy clutch? Im trying to debate on weater it was just a defective maste to begin with or if I need some sort of heavier master cylinder. Is the Type R master any stronger (I doubt it)and will it fit in my 97 LS.
