W/out getting into all the specifics...I've got 2 different questions for 2 very different leagues. Having a tough time making either decision, so looking for some help. I've got my leans for each, mainly with upside in mind...but would appreciate some other opinions. (I get too "attached" to some of these prospects...so even though neither decision is all that important for either of my teams, I make it tougher than it prolly needs to be lol.)

Which 1 of the 4 would you keep over the others?

Christian Colon, Cesar Puello, Kyle Parker, or Slade Heathcott

And which 1 of the 3 would you keep?

Alex Meyer, Matt Purke, or Jenrry Mejia

Thanks for your help/advice.
