auxiliary injection-who here has it?

Alright guys, so what liquid is everyone running? I've seen a couple of you mention it, but it hasn't really been touched on a whole lot. I did more research on this several months ago, but the information is on my laptop that crashed. I had kinda settled on running mostly water with maybe about 10% meth, maybe even less. Mostly just because I'm not planning on tuning up with it (that way if the system fails it won't blow the engine), and because distilled water is readily available and cheaper than running full meth/etc. I've read about some pros and cons about different liquids/mixes, some of which may not be true, but I'll start the list below. Please add and/or correct anything you see fit.

Methanol
Pros-
-Cools intake air more than water, but not combustion chamber
-Allows tuning up (substitute for fuel)
-Won't freeze in the winter
Cons-
-Costs money, but still cheaper than denatured alcohol
-Not as readily available as water or denatured alcohol
-Corrosive to the system, especially if ran 100%
-I've HEARD if it's left in the tank for a while it will turn to a jelly-like substance, not sure how true that is.

Denatured Alcohol
Pros-
-Not corrosive like methanol
-More readily available than meth
-Close to the same octane as meth, and equal benefits
-Won't freeze in the winter
-Allows tuning up
Cons-
-Much more expensive than meth and water

Water
Pros-
-Free from the tap (if you're that brave), or distilled for fairly cheap
-Readily available
-Cools combustion chamber more than meth, but not intake charge
Cons-
-Will freeze in the winter
-Cannot tune up, usually lose HP

I've read about people using HEET (99% Isopropanol) also. And it's been suggested that I use distilled water most of the time, and add just a little meth or whatever for the winter time. However, I won't be driving the car in the winter anyway because it's too hard to control in the snow/ice (and that was with lower HP, before adding the 500R). I'm still concerned about the fluids freezing in the pump and lines though. I've also seen people run windshield washer fluid, but from what I hear it leaves residue and that wouldn't exactly be good for the injector.
