greaseable centers on CV?

[Cornfield creations]

Hello, I am getting ready to call Jess and order my CV shaft, just wondering if I should get the greaseable centers? I know you have to pull the shaft to grease them. I have a TC 4". Just curious if it is necessary on it?

I would if it was me. I don't have them on mine but didn't know that I wasn't getting them and wish I had.
Jesse would know best just ask him.
