What can a 7 1/4 rear take???

Dang! A lot of folks sure have tested these little rears. That's crazy that some people blow the rear right away and others can beat the for a while and not break em. I guess it's luck of the draw. I know a local guy who sells the 7.25 and 8.25 rears for about $200 so worst case scenario I can alwas replace mine if it blows up
