Difference is the replacement pin

The difference is the "replacement pin" (or whatever Shimano calls them) that you use when you are joining the ends of the chain together. The 7801provides slightly more positive "feel" when you are pushing it into place with the chain break tool. With the 7800 pins many people didn't get them seated correctly, and then they had problems with chains breaking (i.e. coming apart) under use.

Thank goodness for a sucessful search!

So, if I understand palewinds post correctly, the 7801 pins can be used on 7800 or 7801 chains? Sorry for such an elementary question if this has been covered.
