glad you ended up picking up the glass screens m8, they help.
id get another cone(bowl/slide) for that pipe just because its a smaller water pipe. then in the occassion that someone comes to burn one aswell, you pack up the bigger, "party bowl".
i have a few slides. one or two have huge holes that are too big, and glass screens and me arent exactly the best of friends. they always find their way into the ashtray, and then into the garbage. So, my fix, if you should lose your screen is to use stems. just take a nug and crack the stem off and just use that to plug your bowl.
"Ew but Dude, you're smoking stems then!"
my stems arent the most delicious thing on the planet, but it also is better than pulling bowls through with out flame.
so i dont mind, and its a cheap alternative to replacing screens
