• I don't think its a case of better, more that it works, and its all driven by the rear hub, you'll get a different chainline with a different sized rear hub, track bikes work off a 120mm hub so you get a chainline in the 42.5 - 43.5mm, if you wanted a chainline in the 46-47mm area what size would your rear hub be? I don't know as I'm just regurgitating what I'e been told, and have come to believe is the truth, if you can get a chainline in that zone without it being a bitch to figure out/get parts for go for it.
