I'm just not sure why you felt the need to give up Doubront+ for Pestano? Doubront misses bats as a starter, he had a sub 4 xFIP last year and his DIPS are all below 3.50 so far this year.
2012 Pestano had more or less the same peripherals as 2012 Doubront, except as a non closing RP. And he's hurt right now.
If anything, Doubront > Pestano IMO.
Being said, it's only late picks being thrown around so you can't really lose hard. Maybe you just don't like FD.
