Basically, any one can choose to do something that best benefits them and their end result, whether by upgrading the current axle or by swapping it out for a tried and true replacement. Yes, it too has to do with your budget, and true, this swap may be only a couple hundred bucks in the beginning, and it could turn out that it can cost you a couple grand in the end, but it's all how we choose to approach it. I chose a Ford 8.8 because the benefits of it outweighed the limited practicality of the D35. Of course I don't have it installed yet (only because I am still rounding up the necessary brake parts), but in the end, my solution can and may differ from that of anothers solution. But, if I knew that I didn't need the higher gear ration, or the LSD, or the added beef of the axle shaft, or the ability to limp off the trail with a broken axle shaft because it has disc brakes to keep the shaft from coming out, then I would have stayed with the D35 and performed the necessary mods to make it more reliable.
To basically put it simple, to each their own.
