main reason for the slides getting tangles is trace is 2 long also the dropper to the sinker is 2 long. with the non- return slides you need to let your sinker bed into the sand really well- long arms are best(were you tie to the sinker). there are different methods for sliding and the Chad does is very good for the beach when you want the live bait in the surf zone. if fishing deeper water or off the rocks or a channel I find the non -return slides best as it gets the live bait down faster and it stays down.
