Well with the 2-piece it won't damage the transmission, because the first drive line never moves. You just might go through carrier bearings a lot.
However, if you get a custom one made, it will be perfect for the truck. Because you give them the measurements from full drop, mid travel, and full compression, and they make the drive shaft the correct length for your application. So its up to you. I don't want seem like I'm trying to talk you into something because its easy for me, I won't do that. But the way I look at it, is maybe $200 now, saves you more money in carrier bearings later? Lol.
