There's really no downside to having sealant in your tires with or without a foam thing. There are advantages to tubeless beyond simply flatting much less.
That was kinda what I'm getting at.. if the advantage seeking for TL is not about flatting less, then with this new tech to start thinking about skipping the sealant. I don't know if this article is accurate; are UST tires the only TL tires that work without sealant? If so, you can ignore everything I suggested unless you're running Mavics, right?
