The best elastic is the preston slip. Take all of the elastic off the winder.Once you have taken the elastic off the winder don’t cut it at all, then push the elastic through the connector and push the
other end of the elastic through that loop you’ve just pushed through the connector. Makesure you have the knotted end is down by the bung. Just makes it easier that way.
The connector will be looped in place now. Then use a diamond threader to thread the elastic through your top kit, all that needs to be done then is to tie the elastic onto your bung.
