Wow, just saw a somewhat similar question and so is the answer. In these areas I use 3-4 ft of 60-80lb Orvis Mirage Fluoro leaders. Learning to play the rocks can be tricky and takes a knack to develop but can be done by most anyone. Once they sound into the rocks you want to keep even pressure but not a ton like your trying to horse them. I like to maintain contact for a feel of what they're doing. Don't want to get rubbed which is why you want some pressure on them. When you feel a little give bring them up/in. If no give at all I may bow the rod or take a wrap or two off to let up for a second or two to see what happens. Trying to encourage the fish to do something like turn, give, relax, swing the other way around a rock or whatever so I can get back to reeling in or the fish taking line.
This has worked many times even when fish have fully encircled a rock and cinched the line down. I have lost one maybe two decent fish in some of the boniest areas employing this technique but landed many nice ones. Hope this helps.
