Which OF to drop?

[plainyogurt]

I currently have Span and Bourne in two of my starting 5 OF positions..strictly for speed..
I have Carlos gomez on my bench..

Which one would you drop to pick up a Strong RP with low whip and era. Here are some available.
Juan Cruz, linebrink, Jim Johnson, Grilli, Thronton, Saito, (any suggestions)

Also is Kip wells, or Taveraz a good idea to pick up for saves, They are available?

Who would you drop? I am leaning toward Gomez, but the twins didnt trade Johan for him to sit on bench...

Any ideas?
