I think Mclaren should wait it out a year, and see what they can get the Honda to do. They obviously have the handling, and changing the car again around a Renault powerplant is just as risky a roll of the dice as they made going to Honda. I think at this point most likely Alonso is gone regardless. I have to agree with Steveaki13.... even if they integrate the Renault into the car flawlessly, they still only have a top 3-4 car.
