Why Livorsi over Gaffrig Performance? Because I would want good quality, american made originals as supplied by Livorsi and not import Chinese junk that Mike Schultz, owner of Gaffrig Performance is trying to pawn off on the world as Livorsi's product. That would probably be the biggest reason!! I think the slight mis-match Livorsi has is some cases is minor compared to the alternative. Something to think about.
