...quick links seem to work pretty well for me. Not sure what you mean by a "press in pin" ? The newer chain pins are often peened, so when you press one in and out again, it enlarges the plate hole and can lead to failure. I know Shimano had those press in and break off pins, but you're not supposed to break the chain in the same place twice, for this same reason. I stopped using Shimano chains for this reason, so I'm not up on what they sell now.
