Shackle Angle

[lifethroughdeath]

I'm going to be swapping my rear 52" leaf springs for a set of 63's that i got a real good deal on. Now i know theres a lot of moving the hangers around and i'm all set on that. My question is pretty generic actually; on a vehicle that has a rear shackle flip, what is the ideal shackle angle i want? Pics would be awesome.

i think it should be about 30-35* toward the back of the truck. that still allows for compression and alot for droop
