First of all make sure the track has no ruff spots in it. Some times when the delrin wears out and they 're not replaced soon enough the pins will start scaring the track. Lighty sand the track with 400wet and dry paper,then with 600. Then use a alum. polish or a polishing compound and polish the track until it's smooth.

This does two things, makes the thing slide better but more imporantly the smoother surface doesn't wear the delrin as fast. Then you can use the two slugs. One other thing I did with mine was to use a smaller line for the traveler and using a sheet bend attached it to the mainsheet. The smaller line runs through the system much easier.

Have Fun
