Interesting, but a little long in that it could have been edited a bit and not lost anything. Varley has a seriously odd sense of humor:
Brenda sat up, wide-eyed. "You're a Heinleiner!" she said.
It was MacDonald's turn to shrug. "I don't attend services, but I agree with a lot of what they say."
I didn't know we had services. Then again, maybe I wouldn't want to drink the soup. In all seriousness, Red Lightning is more tightly written. Actually Red Lightning reads a lot like a Heinlein Juvenile, but with more sex.
