Wide Angle Prop 30 deg or 40 deg

hi guys am in need of a new front proposal for my disco and am looking at a bailey morris extreme wide angle one.

my questions is this do i go for the 30 deg or 40 deg joints.

the 40s is a bit more money but if im going to stress it less then il do it.


i have a:

5" suspension lift all done in the suspension/blocks not using body lift
285/75/16 tires
corrected arms front and rear

With that amount of lift, I'd go with 40...
