Through the years the thinking has changed from short chains so they can't get momentum built up to longer chains, so the aren't pumping your anchor point straight up. Personally I use Berkshires and about 18" of cable, never had a problem. When pulling sets I take a pair of C7 cable cutters and snip the cable below ground level, I don't pull stakes out due to all the solid/rocky ground I trap. I do use shock springs and 4 swivels in the trap chain, 3 links between swivels, shock spring in the middle, last swivel attached to cable. The over kill is for non target catches, the domesticated kind. With drags it's all chain and usually wrapped around a sapling/small tree…..chain lays flat. Hope this helps.
