upper control arm for blue front rocket

[Dirtracer18]

mine got bent Saturday night and I need a new one. I know what length to get but do I get the straight ball joint holder or a 7 10 or 13 degree holder. what effect does the degreed holders have?

I use a 10 but a 13 would probably be better.When you are traveling the r/f a lot it keeps the balljoint stud from bottoming out in the housing.
