The closest thing to a PD on the Wilson side is the Juice 100. Personally, I don't think you will like the Blades if you love the Pure Drive -- that's just my own experience. The Blades provide more of a control oriented experience. But you can always demo it and see what you think!
A couple others you may want to check out: Donnay Formula 100, Dunlop F5.0 Tour.
