Try it and let us know
That's one of the few tanks I haven't tried. The original Herakles was OK in my opinion, but people have been raving about the Plus. If I had to guess, I'd think that it'd be good. If the Triton does TC well, then I'd bet the Herakles has to at least be on par, though I'm sure it'll be better than the Triton.
On the topic of TC, has anyone tried stainless steel coils yet? I'm quite interested in these because they can fire both on TC and regular wattage modes. But your device needs to have Stainless Steel mode...
