Reply to 2x Lemurs + MF Pro or S4 + MF Pro or...?

So now when lemur has now found it's way to iOS, Iv'e been deeply considering selling my traktor S4 and buy a second iPad 2, so I can run Lemur on both of my iPads, along with my MF pro beatmasher (which is atm my favorite controller!) to control traktor pro!

However, could anyone who has used a lemur before tell me if this sounds like a plan or should I stick with my S4 and simply alternate between the lemur/ipad and the MF?
