The two stainless ball chains have a unique feature where we have used a machined acetyl connector at one end and a 3g black stainless connector at the other. This allows the chain to be simply reversed to add weight to the bobbin when required. Also adding the 3g stainless add-on weight integrated into the hockey stick increases the weight further and means that the PTFE bobbin can be used at weights of 5g, 8g or 11g.
