Hi! Yes, that would be a good pair. 60W is probably too much for the Subtank from what I've seen on this forum. Members seem to like the Subtank Mini at 25-30W. Remember though, you don't have to use all of the 60W.
However, the 0.5Ω coil has a 'recommended' wattage range of 15-50W from what I can see online. So you may be able to push it well past 30W.
