I've used 50lb braid for cranks for years with a snap. Hardly ever loose a fish. Just don't horse them. Keep the drag loose.what you feel with the braid is amazing. The 50lb Sufix 832 works great in rocks. As far as the rod I use a mh moderate fast falcon bucoo.You can crawl the crank up and down huge boulders and stop it when it contacts then let it float up. You can feel them suck it in when they strike.
