Luckily I don'the have this problem yet... or at least those area are lowest on my priority list. I don't have experience with yhe vs. Rcg, but I would say you can't go wrong with button bush or rod. You can grow the cuttings in your garden over the summer and get some 5 footers. Also those species can handle partial shade. Maybe go onto state land near you and try to find similar soil conditions to what you've got. Depending on how large of an area it is, you might be able to use a Weed whacker around plantings for extra mobility.
Overall I'd say your best bet is to try a few different things (planting treatments )and see which works the best. Then you can do that one in the future.
