I agree. The weight is what you should go by. I'm using a 2007 era monoprice mount that is rated for up to 175 pounds but states "Up to 60 inch TVs". This mount is rock solid with my Vizio 70 on board.
BTW, indept, how is your 70" Vizio 75 pounds???
Mine, according to the specs weighs 86 lb.
|Net With Stand:||97.00 lbs|
|Without Stand:||85.98 lbs|
