When I read the torah text (parsha or otherwise) I currently use a couple of chumashim with notes, and Rashi. I know some Hebrew but am not fluent. I'm ready to stretch beyond what I'm reading now and would like to add another commentary to add a new dimension to my study. The chumashim I use include some verse-by-verse notes from a mix of Rambam, Ramban, Rashi, S'forno, Ibn Ezra, and occasional others, but not much commentary from any one source.
Is there a common "next step" for torah study? What do today's authorities recommend? What is the typical learning path in yeshivot?
