If you just go on the sand then bfg is not a practical one for you! But if you also hit rocks and hard Mountain tracks as a combination then they are perfect!
Same here ! Driving fzj80 with 300k miles ! Lots of variety harsh offroad driving!
LSD also helps better corner handling in high speeds which lockers are not designed for that!
Using rim 17 ( Gt wheels) 285/70/17 and spacers for last 10 years ( on the 3rd set of tyres now )
Lots of offroad and highway mileage! So far no problems with spacers !
