for party, which strain?

so for the party in the forest next weekend some friends and i wanted to do some shrooms, some weed and some mdma crystals.

but could anyone recomment a kinda strain for that? i've read that c99, trainwreck, nev.haze are better for when you are with more people, that you are less afraid for a busy enfironment?

we were discussing weather half a portion(about 15 grams) of c99 or a whole portion of trainwreck would be better. it are low dosages, but with the mdmacrystals and psychedelic music and lights it will be trippy enough.

what would be more suited, and wich more trippy?
half c99/whole tw

thanx for any replies,

mory
