alright with all this R&P shit, first, most of the rover R&P failures are due to the halfshaft breaking and therefore causing the ring to break loose and go crazy. This is eliminated with a locker of somesort, like and ARB, TT or a DT. Now, you got those and it's going to be extremely rare for a stock 3.55 R&P to break but it can happen.
As for the 44 argument, we've been here before. A 44 is a waste of time, especially in a rover due to the extra fabrication. You can have a stronger setup going a full 30 spline toy front and rear or even FJ80 axles. If your doing fab work and want improve strength you go with a 60. Cost is the only downside. But if you go 44, you will end up going a 60 anyway if you are breaking rover shit even now, because you?ll still be breaking 44 junk too.
bottom line:
stock rover axle < stock 44
built rover axle > stock 44
built rover axle < built 44
built rover w/ toy parts > built 44
built rover w/ toy parts < built fj80 axles
built fj80 axles > built 44
d60 > than any combo
that's my rating and if you don't like it fine!
