I can't really remember if I found it dry when I tried my tester a while back.
Since I'm not familiar enough with these flavors to pick out a culprit, I did a quick skim of the ELR notes for each and, to my surprise, did not see dryness mentioned often for any of them. I would have suspected the cinnamon or cereal (or the cinnamon-cereal!) to be most likely.
I have seen Cream Fresh mentioned (at least once anyway) to help combat dryness - not sure if that is evidence enough to rule that out or not.
In some older threads here, there was mention of adding a little meringue or marshmallow (or even EM!) to help a dry mix. There was another reply, of course, that warned against EM or marshmallow due to the possibility for muting.
Also, distilled water was mentioned in those older threads but seemed to cause folks problems with spitting, popping, or such. I don't see it mentioned much anymore so guess it is not a good solution.
So, I guess that leaves me stumped as to offering any really useful advice at the moment.
