I ended up buying the Tornado Stealth 80 to go in my Bolt 30 watt tube combo.

Next to my Bolt 60 with the Tornado 100, these amps which otherwise sound identical, sound very different with these pictures. The Tornado Stealth 80 is very tight in the low end as advertised, and possibly a bit aggressive (I'm not big on metaphor when talking about sound), while the Tornado 100 is "rounder" and has more even-frequencies all around. Of course, the Tornado 80 is brand new and so I suspect it will take a few months to really hear what the speaker will end up sounding like, but for now I'm mostly satisfied.
