I'm assuming you are using a 5 man rotation, because having them in a 4 man, which means they'll be pitching every fourth game, with a total of only 205 innings between them, you will likely run into some serious fatigue issues (especially with the 89 inning guy), even if you set them at 40/40. As a point of reference, I currently have the 125 inning Cy Morgan and 88 Chamberlain (135 innings) in a 4 man rotation as a tandem, and even they aren't back to 100% each time through the rotation despite being set at 40/40 and 40/50. While it should be noted that my guys are pitching at Coors, which will definitely cause much quicker fatigue, but rightly or wrongly, I still am of the opinion that you will have a hard time keeping them fresh throughout the season, even at the lowest possible setting of 40/40.
