Revision from lapband to DS.

Hi!  I am new here. I am a 43 years old female  5'7" and currently 260 lbs.

 I had the lapband in 2005 and was successful in loosing 125 lbs in which I kept off until the birth of my son in 2010.  With time, I have gradually gained a large portion of weight back.  I have been Dx with a slipped band.  My surgeon has given me the choice of rny or DS.  I am leaning towards the DS because the statistical data documents a greater rate of keeping the weight off long term.  Has anyone been through a similar experience?  If so,  what are you pros and cons?  

Thanks!
