You should consider using a float and jig type approach. When fish are stacked, you spend more time fighting fish that actually wanted to strike (no flossing or snagging) and less time wrestling and harassing non biters that are snagged in the stomach (tail or whatever).

When I was fishing for pinks and silvers stacked in the sky, and chums stacked in both hood canal and flaming geyser - and only snagged 1 out of 10 fish (and never when I was using a float - which was most of the time).

In fact, if you use a pink and white marabou jig (other combos work too) you have a great chance at catching any of pinks, silvers, chum, trout, and steelhead - especially if you tip it with some prawn meat.

The nice thing about floats is that your line and hook are always (95% or so) above the fish - so incidental snagging is nearly eliminated - without losing your effectiveness at catching fish.
