Which 3 of these four starters would be  SP 3,4,5 and why? If it matters, my C has a PC >80. I am thinking Reed and Riggs due to the high splits and Pavlov because he has better VEL/Flyball and better pitches.

I don't get hung up on SP's beyond my #1 and #2.

What I typically do is give them all 3 to 4 starts to get a little bit of a body of work under their belt.  After the third of fourth start of the season, juggle the rotation based on the performance of your 3/4/5.  Whoever bubbles to the top becomes #3, then #4, then #5.

This can and most likely will change (multiple times) as the season progresses based on performance.

Reed is hurt so that may solve your problem.  Riggs appears to be the best of the bunch.  The other two may work in LR but it will be a long season if you're looking to get 30 starts out of them.  Weak splits and pitches are bad qualities for candidates for the rotation.  IMO you over paid both Pavlov and Gardel, there had to be better options that would have taken less.
