Which Base MSI to Use For Adobe Reader Updates?

Question

I am new to creating AIP for Adobe Reader and am wondering which MSI to use as the base installer.  From what I understand, to create an AIP for Adobe Reader 11.0.07, I need to first have the AIP created for 11.0.00 and then patch it using the 11.0.07 MSP file.  (the 11.0.07 MSP file contains all other updates found in earlier quarterly releases and OOC releases)
So my question is on obtaining the correct MSI file for creating the original 11.0.00 AIP.  My options for obtaining the correct MSI are threefold:
The original 11.0.00 MSI (AdbeRdr11000_en_US.msi) (only one msiexec comand required)
The original 11.0.00 EXE (AdbeRdr11000_en_US.exe) (extract the files from the exe, then run the msiexec command)
The new 11.0.07 EXE (AdbeRdr11007_en_US.exe) (same as previous item)
I noticed that the MSIs in the AIP are named "AcroRead.msi" when extracted from an EXE file (#2 and #3 above) but named "AdbeRdr11000_en_US.msi" when extracted from the original MSI file (#1 above).  Are all three of these resulting MSIs the "same"?  They all have different MD5 hashes but otherwise appear identical.
Once I have the original AIP for 11.0.00 backed up, I should be able to reuse it when new quarterly releases come out.  Can anyone help please?  What is recommended?  Thanks!

No one answered, but I think probably all can be used.  I made a script that will automatically extract and build the AIP from the most recent EXE file provided by Adobe.  Why Adobe doesn't create a new MSI themselves is beyond me.
