Anything on these two?
I think Einhorn is good, at least as far as LRW goes. So much of LRW is just writing stuff and hoping it doesn't suck but not really knowing what you're doing. That seems to be the nature of the beast across the board. I think that the exercises she gives you are decently helpful, and personally she seems nice/cool. She's a good person to talk to outside of class because she's pretty well connected in the TX legal world and can give good advice on stuff like legal internships. She also keeps it pretty real and knows at what point in the semester people haven't done the reading or whatever and doesn't give you a hard time about it.
Speaking of reading for LRW: for the most part, I think it can be helpful. Most people won't really do it (guilty as charged) and you can do well without it but actually reading and applying what you read will probably give you a leg up on most of your classmates. But YMMV I guess.
