Preference in drives shaft direction?

[flyin ryan]

I notice some people like to run the slip yoke part of the drive shaft towards the third member or towards the t-case.  Does anybody have a reason why one way would be better than the other? Thanks.

hollow vs. solid, what would stand up better to a rock, thats why some of us run the slip at the diff end.......

I would do that but i can't, i have 2 different flanges on the rear third and the t-case.
