Help with race wheel choices

I am back to the sport after a 2 years of getting fat and restoring old Corvettes…anyway I am back to training and racing with my main race being IMF (this will be my 4th go) Living in GA, most races are not too hilly.
I ride a Blade and I am considering: 1.HED 3 front and rear all carbon 2. Zipp 999’s 3.Zipp 808’s.

Opinions?
Thanks in advance!

H3 front disk rear.
