Which Kadee is best?

[Anonymous]

I am in the process of changing the couplers on my "old" locos. I have a mix of Athearn and Atlas(Roco and Kato). I had some information on which coupler was to be use on a certain model like an Athearn GP38( #37 or 38) but a #5 did a faster and job. Is there a chart somewhere? Keep in mind that my locos are from the 70's and the newer are from 4-5 years back.

Thanks for the help
