Is a 7.25 rear strong enough?

cryo treating in and of itself isn't that expensive, about $150 for a R&P, but when you start to figure in all the other ancillary items the return becomes less ideal. shipping a R&P back and forth, buying a SG unit if you can find one, buying another R&P in your desired ratio if needed. then all of the consumables to rebuild everything...

all of a sudden a whole 'nother rear end starts to look a little more enticing...
