I still believe that most people that run a poly set probably would have been good running a solid setup in the first place. The biggest reason there's a lot of poly in suspension components isn't because it's ostensibly better, but because in large enough quantities, the stuff is damn near free to produce.

And yes any subframe connector will be an improvement, and it's true that you want that connector to integrate directly with the rear frame. There are many versions that don't really do that.
