I use cheap grocery store vodka in my airlocks,& no misty stuff. And it doesn't foam out the lil holes in the airlock cap like starsan does.
Doesn't evaporate very fast at all,especially this time of year.

I've used filtered tap water for 15 years without any problems. Evaporation is relatively slow.
I've recently tried vodka with no problems. Evaporation is a lot faster than water.
I've used distilled water recently also with no problems. Evaporation is relatively slow.
I've had all drip backwards into my brews without any ill effects, then again I believe that I have pretty good tap water in my area.

For years I was disheartened by the occasional suction of my airlock contents into my beer. I now know that the wort needs to be below room temperature before going to fermenter and pitching yeast so that as the wort warms up a little the pressure pushes out, rather than the wort cooling a little bit to room temperature and suctioning into the fermenter. I also make sure to add room temp water to the airlock for the same reason.

Better yet, S-lock airlock are my favorite if you're not limited vertically. Fill about 1/3 way to max fill line and never a worry if it ever suctions (and it does when it goes in a fridge to crash cool).

I would think twice about using a strongly flavored liquor like Raki in your airlock, unless you like your beer tasting like anise.

Why is a few drops of suck back going to affect my 6 gallons of brew?

Raki is, as I'm sure you know, heavily anise flavored. If you've got an ounce or two of it in your airlock, the whole thing could easily get sucked back into your fermenter, and I wouldn't be surprised if that affected your beer's flavor.

To my mind it makes more sense to use an unflavored spirit like vodka. You can buy a relatively cheap bottle of it and use that, that way it won't impact your flavor profile if it gets sucked back in.

Just my .02

Okay, you won me over with your argument....
No more Roki for me, I will use vodka from now on
