Weird Fantasy Baseball Question...?

Our League has 3 DL Spots Avaialable to each team, i currently have 1 spot filled with Akinori Iwamura, but he Appears to be out until at least August, i was thinking about adding someone else on DL currently, who is expected to come back sooner.. Should i add Maybe Carlos Guillen, Mike Aviles, Alex Gordon. Those are the top 3 Available DL people. When they come off the DL they will take Mike Lowell's spot on my roster. There is no active player worth adding over Lowell at this point, the best one avaiable is Rafael Furcal. This is a DEEP league. So should i consider adding Carlos Guillen, Mike Aviles, Alex Gordon, sorry for being so long and boring. I will give best answer. thanks
