The welded diff puts a lot more stress on the carrier and shafts, keep that in mind. Even making turns on pavement will take it's toll on the life of those parts.
As for the front, a spool/welded spiders are super hard on parts. Even with 31's, your frame and steering system will see a lot more force (with more force on the frame and steering parts) and you'll have difficulty steering. I wouldn't recommend a welded rear for any vehicle, even trail only. Unless its a 14bff
