Fsx Control Null Zone Settings With 777 Sp1

I normally keep slight null zones (approx. 5 units) in FSX control settings.  With the new FBW implementation in 777 SP1, is it recommended to remove these null zones and let the internal PMDG FBW null settings set the null zones?

For what it is worth, it appears that FBW behavior is improved with the FSX null zones set to zero.

Thanks!
