Sorry for the late reply, long workday. The Herakles is a good tank. The coils are great performers. The .6 coils provide more than enough flavor and vapor. I normally do my builds around .4-.3, and the .6 coils are quite comparable to that. However, I can't help but to point out that Herakles coils are high wattage coils. In order to get the best performance out of them, it's best to run them at 60-75w. With only 60w at you disposal, the .6 coils would be the better choice. The .2 coils require even higher wattage.
