Testing my various soap recipes!

I counted them up, I have 28 different soap recipes!  They range from just 4 days old to over 12weeks old.  I think I am ready to start using them in the shower.  I'll use the oldest first.  I want to wait until each of the soaps are at least 4 weeks old before I use them.  I plan on using each bar of soap for 3 showers to evaluate the qualities.  I'm going to have a whole line up of soaps in my shower.  I cannot have 28 different recipes in my repertoire.  I'll have to narrow down.  If I don't notice any discernible difference between recipes then I need to evaluate which ones are worth repeating.  I want to try all the soaps before I give any away just in case something is wrong with any of them.  I don't plan on making any more soap for right now, unless I have an overwhelming urge to make some, which likely will happen anyway.  However, I think I've pretty much made the different major categories of soaps that I wanted to make.
Castile
Milk
Honey
100% coconut oil
Salt Bar
Lard Bar
Whipped Soap
Coffee
Beer
Oh, the coffee soap with coffee grounds soap I made I put in WAY too much coffee grounds.  It's exfoliating to be sure, but painfully so.  I'm not sure what to do with them.  Should I leave them as is, or cut them up and rebatch them with new soap to mellow out the coffee ground ratio, or just toss them.  I'm leaning towards shredding them up and mixing them in with new soap.   But what new soap to mix them in with?  Hmmm…  I'm hoping my soap testing will narrow the choices down.
