FtM: Best binder for someone whos big and tall?

I'm 42D myself, and my favorite for binding is the Frog Bra, but I'm not sure it's being manufactured any more, unfortunately. Underworks makes a tri-top binder that's not too bad. It binds well, but it doesn't breathe as well as the Frog Bra, it isn't as soft, and it isn't stretchy at all, so it's much more difficult to pull on. The X-large was a tad loose on me (because my chest is actually 41"), so the large might be just a tad loose on you as well, but the medium might be too difficult for you to get on.
