I did not see a reply as to wheather there is any DISadvantage to single's



Yes there is a disadvantage. The single beadlock will have much more clamping force on the bead than the side that has screws or glue, this will make the sidewalls wear unevenly and M/T and Weld wheels strongly discourage single beadlocks and they both consider them to be unsafe, however there are lots of guys getting away with the singles without issues
