More experiments?

Due to the success of the vodka experiment, I'm thinking of trying two other experiments...

• If filtering skank vodka turns it into primo vodka, what would be the effects of filtering primo vodka? Would it be better than the filtered skank vodka, or would they both be reduced to a "lowest common denominator"?
  
• What happens when you filter other nasty, cheap alcohols that are often carbon-filtered (in particular, whiskey and scotch)? Can I do better than Jack Daniels or, dare I say it, Chivas Regal, for less than $6?
  

I think I'll wait until we actually drink the vodkas before moving on to new experiments. For, while we shouldn't stand in the way of science, nor should we forget the fruits of our labor.
