I don't worry about the spit. Who cares. It's mine. Also, the vinyl tubing I use is see-through, and you'd be amazed at how little spit actually gets under there while smoking.

I use food grade vinyl tubing that has 0 flavor too it. I have chewed through one once and it had absolutely no taste to it at all.

The tubing is thick, and takes time to get used too. If you think softie bits are uncomfortable, then the tubing will be unbearable to you.
