The arcs where the Hulk has to face his inner demons are also great Sal Buscema Hulk stories. He has a unique way of showing the Hulk's internal struggle, not just his physical battles. You can really feel the Hulk's pain and his fight to control himself or just let loose, and it's all enhanced by Buscema's art style.
I'm not sure specifically what 'robin raynelle the big sal story' is. It could be a personal story, a fictional tale, or something very specific within a certain community or family.
