Currently Re:Reading the SM manga

[HopeSeiketsu]

I only have 5 volumes at the moment and was wondering which version I should use for the download of rest. My manga reader for android Mango(not on the android market but GREAT manga reader does most of the stuff paid manga reader apps do for free with SEVERAL sources) has several different versions for me to download and I was wondering which I should. It is from the MangaHere s7te for this one as I prefer that source though I have access to ALL the major sources.
