i second the idea of jsut going with a low dose LSD. lsd at low doses is quite mild, friendly and euphoric, and is quite controllable. somewhere around 80-100mics is perfect for this.
2cb is nice as well, but for me at least, it retains a lot of the 2c character, which not everyone gets along with easily. that said, it is the friendliest of the 2cs, and though i dont find it that euphoric (streight up euphoria that is) it has a really nice tendency to make everything that little bit better. low doses work wonders for a night out.
aMT.... i think this one is the one with most variability. some like it, some learn to appreciate it, while some jsut dont have a taste for it. it can be very mdmalike in some experiences, or very psychedelic for others.
actually, now that i phrased it like this, it reminds me a bit of what 5-meo-mipt is for some. some find it energetic, euphoric, sexual, while others get really deep into the psychedelic realm on it... hmm, perhaps you can also explore this possiblity? for instance, for me a very low (almost threshold dose) of 5meo-mipt was quite nice for a night out. much energy spent dancing, feelings of connectedness... and though some lack of clarity became apparent later in the trip it was nonetheless enjoyable...
but then again, perhaps you are not looking for such low profile experiences...
guess what im trying to say is, you will proabbly have to read a lot and even try some things out yourself before finding what you are lookign for, seeing how variable things can get
best of luck
