Lineup dilemma - WHIR

[KenDawg19]

I am in a 10 team dynasty league and signed Aramis Ramirez to a 2 year contract and Brian Roberts to a 1 year deal in the offseason. Both of my DL slots are occupied with Roberts and Ellsbury. I currently have ARam occupying a bench slot with Glaus as my starting 3B. I am a little weak at SS with Starlin Castro as my starter.

1. Do I pick up a SS like Furcal or Aybar, move Castro to the bench, and waive ARam?

2. Do I drop Roberts, move ARam into a DL slot, bench Castro, and pick up a SS?

3. Do I stick with Castro and hold onto both ARam and Roberts and hope they can help me for a playoff run in the 2nd half?

Please help! Leave a link to yours.
