Review of RY4 Double Flavor-TFA:

This is hands down the most versatile flavor I've found, and it tastes GREAT as well. Great as a stand-alone flavor (with a little AP) but mixes so well with so many different flavors, peanut butter is a favorite of ours, this is a great one to experiment with. One flavor I highly recommend, especially to new diy'ers, due to it being so versatile and forgiving. I also think that this is a flavor that would appeal to a broad range of pallets.
