Those two are currently/so far my fav’s because they have shown me the most obvious and easily seen/felt effects. As a fairly new member, I am still becoming acquainted with the effects of the pheros I have so far accumulated.
I like MX300 in situations where I want a little more confidence and less sensitivity, such as at work or when dealing with people who I know to be regularly unpleasant.
CTTM2 I like just because the effects, the first time I used it, were dramatically obvious.
I know what you mean about emergency mixing, even though you’re not quite ready, I’ve done it myself
