I thought I saw a thread about couplers and can't find it. I did a search and didn't come up with what I am looking for. I have come to a decision that I want to be consistent with the trains all having the same coupler. I have my Bachman starter set that has the EZ mate knuckle couplers, but I picked up a couple others that have a different one, not sure what it is. Does anyone have an opinion on the coupler they use and what is good for HO?
