mooring pennant attachment

I'm going to be mooring my boat this summer for the first time and am looking for insights into how others attach their boat to the mooring pennant.  Specifically, what size line is attached to the mooring chain and what type connector is ued to attach to the mooring.

I wanted to clarify. 
The question is how do you attach the mooring pennant line to your Flying Scot?   I'm thinking about using a large stainless marine carabiner on 3/8" 3 strand line, coming off the mooring chain.
