Williams,RBR - Renault/Ferrari did Webber make the right move?

[Pro Racer]

well Williams got in the points at shanghi and RBR missed out (probably because Massa the mature racer went into hiding and Massa the Basher showed its ugly head again) and williams ae having a reasonable finish to the year (as they usually do) at least the mechanichal faliure's have gone and with a string of consistant 10th (midfield) places webber has done well.

but with the faster Toyota engine will Williams be more competitive or will they be midfield like the factory team with a good engine but crap aero and only be competitive at monaco and the other few tracks they are competitive at?

will Newey make a better car for RBR aero wise and will they get the renault as Newey wants or will they be stuck with the (apparently rev reduced ) Ferrari and will they be up front or like williams still midfield with a good engine?

so did he make the right decision by moving to RBR or would he have been better off staying with Williams?

i think Newey can make a decnt car with either engine but a bit better one with a renault as he did want the renault engine so i think MW made the right decision.
