I have the Tri-Top XL as I'm a 40DDD. It binds ok and I can pass from far away. I like the tri-top because of the wide coverage. I wanted to buy another one to add on to the one I already have, but I know the tri-top is triple compression, isn't it? Is there another underworks binder with similar coverage that I can get other than the tri-top? Has anyone used 2 tri-tops at once before?
