what x-spec parts should I put on my evo 90

[Hovernut]

I had an unscheduled landing with my beutiful Evo-90 an it is in need of some repairs, I cracked the lower frames, and messed up the tail boom and tail case. anyway, I am getting a crashed x-spec for doing some build work for a friend of mine and I am wondering besides the lower carbon fiber frames, what other parts from the
x-spec should I use on my evo-90 I know the evo head is supposed to be better, but what about the center hub and the tail pieces.

any opinions helpfull

Thanks
