MLB or DD Starting Pitchers?

If you look at the top 20 teams on the leader board most of them will exclusively use Diamond Dynasty pitchers in their rotation.  I think going with a Diamond Dynasty rotation is probably the most effective approach because you never know how an MLB pitcher is going to perform unless you very familiar with him.

With MLB pitchers, I've had some success with those elite guys like Felix Hernandez, Justin Verlander, and Yu Darvish but it seems like they always have that one bad outing every once in a while.  Also, Verlander was recently selling on the market for 25M.  It's hard to pass that kind of money up.

Diamond Dynasty Scouting Report

sgorm
I had a comfortable 6-1 lead after 5 innings so I brought in A.J. Griffin to see how he pitched.  Griffin's changeup and curve ball are supposedly very slow.  In this game, Griffin got tagged for 6 runs in two innings.  I'm starting to think that maybe using only Diamond Dynasty pitchers is the way to go. 

Every pitcher I faced on sgorm's team was a sidearmer.

JohnnyHopkins_
I faced two of his pitchers and, from what I recall, there were no four seam fastballs in their repertoire.  JohnnyHopkins_ likes to work fast.  He had a few balks and also didn't appreciate my batters calling time.
 
Interestingly, the two pitchers of mine that JohnnyHopkins_ faced happened to be "factory issued" sidearmers.  I have never changed a pitcher's motion to the sidearm type unless I was trying to recreate Dennis Eckersley so having two sidearmers appear in the same game was rare.

KiNgSriz
Game was played at Coors field and the connection was very smooth.  KiNgSriz will swing almost at everything and is able to make at least some sort of contact no matter where the ball is thrown so be careful how you pitch to him.
