Actually that was the very first thing I did after receiving the TM2. At the time I didn't know any better, lol. It worked but I had to stir in between hits and the extraction was uneven. I quickly learned that I like small bowls to enjoy the flavor and extract in one or two hits. When I packed a fat bowl the first time, it worked, but obviously the flavor diminishes quickly after the first couple of hits. Therefore my personal choice is small bowl= better flavor & even extraction. But yes you can certainly do it. And as a side note that was before I had any other stems so it was with the long Titanium stem that the TM came with. So if you wanted to pack a large bowl for on the go, you can. But here's the deal, it requires too much taking the stem and stir, hit it and then take the stem out and stir again and so on. I see that as too much messing around with it to be doing it on the go. I'd rather load a small bowl enjoy the fresh couple of green hits you can get off of that and then reload until you are good. I usually hit two small bowls and then I'm good for an hour.
