I think you keep Brunner, for a couple of reasons:
1) He's heating up and starting to play very, very well. Can't see how Boyle would be an improvement this season.
2) In a roto league I like Schultz more... but it's H2H. You really should not be carrying more than 4D. Ignoring positions, Brunner is a better play than Schultz. With 2 util spots it's a lot easier to get a lot of play on Brunner - you're not going to hve to bench him on game days anyway.
