I have the ORD flip and will most likely stick with it, cause its what I already have. When its time for 56s, I can flip em side to side and still use them. Thats nice. DIY's big advantage is the ability to use normal 2-plate shackles... so you aren't stuck with the factory ones (short!) or lowering ones (beefy enough for offroad?) or making your own (definitely not as simple as the 2 plate kind!).
