Everyone to their own, but why would you start with a male and female, wouldn't you be better off putting all your time into one. The problem is its like having two pups together you'll always take to one over the other and then the other one gets left behind. The male will tame quicker and respond much faster as it has less weight to lose also they are usually a lot more laid back and easy going. Good luck with them, keep us posted on their progress!
Nice hybrid, I know several people flying Ferruginous/redtail's and one with a redtail/Harris, keep us posted.
