I don't see the F-bomb getting much love in this thread. However, I do love mine.
Perhaps I'd love it less if I were using something like a D020. However...I can use my F-bomb in my bed. To me that counts for something.
For me, it's because my Davinci Ascent is already quite long, then add a WPA stem, and it's now almost 11 inches tall BEFORE I connect a PNWT to it. I want to enjoy it, but it's an awkward setup. I'm going to give it another shot when I craft a WPA for my Indica vape which will drastically reduce the height and hopefully make for a more enjoyable experience
