You know, even if you try and manipulate your health for what you think are prime black out factors, you still may not because everyone experiences G forces differently.  There's no set way of trying to get one or not.  Heck, even with me, I get deep grey outs or near black outs on Invertigo a lot, but there are also times where I don't.   I thought I'd grey or black out during my rides on I305 but didn't.  I will say I do consistently grey out on Millennium Force between the bottom of the first drop until the first camelback hill.  In addition, it the amount of G's on an element isn't the only factor in black outs.  How long they sustain is another key factor and with Pantherian's speed, you're blazing through that course.  The only turn that really has a chance at grey/black out is the one at the bottom of the first drop, which, keep in mind, was redesigned after its first season along with trims on the first drop because of the amount of people experiencing black outs being reported.   I also feel if you're relying on a black out to enjoy a coaster, you might be enjoying them kinda wrong....

I'm used to seeing the brown train sitting on the transfer tracks when they do 2-train ops. I'm not sure about the rest of you, but the brown train normally gives one of the more "rattly" rides of the three IMO. I can remember this as far back as when Diamondback was brand new. I rode it religiously it's opening year and the preceding years and my memory always goes to the brown train giving a more shaky ride experience. Last year I think was the first time I can recall it not being as bad as it normally is. Again, just my opinion. Others may feel differently than myself. 

What will happen if I don't stay hydrated? I'm probably going to skip breakfast and lunch on the day I go and I'll make sure its a hot day.    I want to black out. A full-on blackout. 

I think you got it. That makes sense.
