So I’m going to a rave tonight and its going to be outdoors. Should I just stick to club mixes?
I was thinking of using either tuth or ammo with IS and IH. I typically use ammo x 2, IS x 2, and IH x 2 at clubs and parties and get good results. Should I add an extra dose of ammo or tuth because I’ll be outside? Any advice is appreciated. Thanks! 
IS, nols - so IO &/or IH, P83, P103, MX297, would all be bang-on for a rave environment IMO. Anything fun/social, light, happy, engaging or disinhibiting. 
Outdoors is a bit of a bummer though as your diffusion is going to be far less effective, so get yourself right into the crowd and look for hits up-close.
Tuth or Ammo - Again I’d keep it basic, probably just TUTH as your IS/IH will probably be moderating enough and the dancing/muntedness tends to make the hits/responses decidedly unsubtle!
And yes, I’d tend to err on the high/overt side for dose, so whatever your sweet spot is, add more.
Smell may become an issue because of the activity/sweating and none breakdown, so maybe carry an extra cover scent for later-on but then again, if you ain’t a bit sweaty at a rave, you ain’t doing it properly!
Have fun!
