About the only papers ive found that actually change the flavor of the smoke are Ventti Licorice papers, taste disgusting though I have tried a few of the cheap hornet papers and what i found with them is you do get flavor on your lips from the paper but the actual flavor of the smoke doesnt change, im guessing its pretty much the same with most
I use a lot of flavored papers, but it's only because my wife thinks it makes the joints look cooler, and you get a little taste on your lips for the first couple of hits. Other than that its all for show.
There is something cool about rolling up some Pineapple Express in pineapple papers, or Strawberry Cough in strawberry. lol
