I have a big bottle of Floid Blue and I love it, but I find the Epsilon to be close enough in scent and just as good in performance. So, I say that I won't ever pay a big premium for Floid Blue again. Epsilon basically copied Floid's ingredients. I've read the labels carefully. The biggest difference for me is Epsilon has a little bit stronger fragrance. I will also probably keep some Barrister Reserve Cool around as long as it is available. It doesn't have any coloring added, so it isn't blue, but it smells very much like Floid Blue and Epsilon Blue Med. I find that it has a bit more menthol than the other two and some added skin food. If you get the Reserve Cool, always shake it well before using.
