Green glue is on its way. I am going to start to stop sound between my condo and neighbors condo on shared wall.

I was wondering if not considering any cost other than the GG, would it be better to go 50% coverage x2 (DW GG DW GG DW) or 100% (DW GG DW). Only my side will get coverage. It now is a stagger studded wall with 2 layers of DW on each side. Works great until you get to about 175 HZ. Attic and floor transmissions to be dealt with later.

Thanks
