You must not be fishing the rocks because this is terrible advice if you're fishing where I fish. Maybe if you substitute the sinker for a split shot u may be able to hang. Most of your bigger fish are going to hit the bucktail/jig head period, that is if it is fluttering down and not dragging in the sand like your 1oz sinker.
I fish mostly inlets, piers. open beaches and some jetties. I have never had a problem on the jetties with a coin sinker. The idea is your teaser hook is in one spot quivering, fluttering and gyrating. If you put that where a fish is, they bite. I also fish light bucktails and do good with them.
Note: I usually fish the light bucktails without a teaser so they do hit the bucktail.
The idea of the dropshot rig is bouncing or hopping a few feet and then letting the rod tip tap,tap,tap.
I do not know how deep into the rocks you go, I tend to fish the edges of the rocks. Maybe this would not be an effective rig for where and how you fish but it works for me.
